Last summer, phone maker HTC raised eyebrows by announcing it would enable users to unlock the bootloaders on some of its most popular phones, enabling technically-inclined customers to root the devices and install custom operating systems or, really, any darn thing they like. Now, HTC has come through, releasing a tool to unload the bootloader on phones launched after September 2011. HTC also says it is working to make the bootloader operational on phones launched before September 2011.

The company has offered a complete list of devices currently supported by the tool. HTC notes some devices may never be supported by the unlock tool due to operator restrictions.

HTC had previously gone to some lengths to lock down bootloaders on its Android devices—partly as a defense against malicious software—but reversed course in the face of strong feedback from technically-inclined customers who feel that the ability to install their own custom operating systems is a key element of Android’s “openness.” (HTC says it was “overwhelmed by the enthusiasm of our fans.”) After all, what’s the point of an operating system being available as open source if programmers can’t download it and install it on devices?

For ambitious users, unlocking the bootloader may be a quick way to get Android 4 Ice Cream Sandwich onto HTC devices without waiting for official updates.

HTC is clear that it not officially supporting devices that have been unlocked with the bootloader, merely allowing users to unlock their devices at their own risk—and may mean they’re no longer covered by device warranties. HTC also notes that it’s possible unlocking devices may have unintended consequences, including overheating.

Ryan:  Ultimately, the main reason why I sold my HTC Desire Z and went back to BlackBerry was because of the buggy HTC Sense interface.  I am glad HTC is giving its customers more choice by allowing them to use a bootloader, “at their own risk” of course.

A well-known expert on mobile phone security says a vulnerability in a widely used wireless technology could allow hackers to gain remote control of phones, instructing them to send text messages or make calls.

They could use the vulnerability in the GSM network technology, which is used by billions of people in about 80 percent of the global mobile market, to make calls or send texts to expensive, premium phone and messaging services in scams, said Karsten Nohl, head of Germany’s Security Research Labs.

Similar attacks against a small number of smartphones have been done before, but the new attack could expose any cellphone using GSM technology.

“We can do it to hundreds of thousands of phones in a short timeframe,” Nohl told Reuters in advance of a presentation at a hacking convention in Berlin on Tuesday.

Attacks on corporate landline phone systems are fairly common, often involving bogus premium-service phone lines that hackers set up across Eastern Europe, Africa and Asia. Fraudsters make calls to the numbers from hacked business phone systems or mobile phones, then collect their cash and move on before the activity is identified.

The phone users typically don’t identify the problem until after they receive their bills and telecommunications carriers often end up footing at least some of the costs.

Even though Nohl will not present details of attack at the conference he said hackers will usually replicate the code needed for attacks within a few weeks.

The No. 2 bestselling Samsung smartphone in history won’t officially see an upgrade to Android 4.0, leaving owners to decide among buying a newer phone, sticking with Android 2.3, or hacking on a custom build of Google’s latest mobile operating system. The reason Samsung won’t be offering such an upgrade? According to Samsung Tomorrow by way of the Verge, Samsung’s own customized TouchWiz user interface is the answer, which sounds more like a lame excuse than a valid explanation.

Samsung’s Galaxy Tab—a 7-in. slate I’ve been using daily for more than a year now—is also on the “won’t see Android 4.0″ list, says the Samsung Tomorrow blog. I can understand we’re looking at a smartphone and a tablet that made their debut in 2010, and there’s a limited shelf life for future updates on mobile devices. What I don’t understand, nor accept, is that the issue is Samsung’s user interface software. Even worse, I think Samsung is shooting itself in the foot. Here’s why.

You have to treat current customers well. On the one hand, I can see Samsung’s stance if it chooses not to bring Ice Cream Sandwich (ICS) to these older devices. From a financial standpoint, those handsets and tablets are already sold, and Samsung has earned all the income it’s going to from the sale of such devices. To bring Android 4.0 to the Galaxy S and Galaxy Tab, the company would have to invest time, effort, and money to deliver the software. It has no financial incentive to do so. But customers don’t care about that and could decide to buy a competing product if they feel slighted.

Software add-ons should never stop product advances. Some people like TouchWiz, and some don’t. The same could be said for HTC’s Sense. Both are user interface add-ons atop Google Android, and neither should be the primary cause of stopping an Android update. HTC once fell into this same trap with Gingerbread on its Desire handset and eventually compromised by removing some custom apps to make room for the update.

This isn’t a technical issue, it’s a bad decision. My first thought about this situation was that perhaps the Galaxy S and Galaxy Tab didn’t have the horsepower to run Android 4.0. Yet the Nexus S, made by Samsung, will get the ICS software, and it has very similar specifications to the Galaxy S in terms of memory, storage capacity, and processor. And I’m willing to bet the Android enthusiast community will have a custom build of Android 4.0 for both devices, if it doesn’t already. How sad is it that external developers can make this happen, when Samsung can’t?

Will most people who own a Samsung Galaxy S or Galaxy Tab be in an uproar over this? Probably not, as they’ll likely never know about Samsung’s decision, nor will they be thinking about Android 4.0 for devices that are 18 months old. But the decision sets a bad precedent and suggests that Samsung is more concerned with selling newer hardware than supporting existing customers and their current devices.

My suggestion would be a compromise of sorts: Offer a stock version of Android 4.0 for these devices with the customer understanding and accepting the fact that the TouchWiz interface will no longer be available after the upgrade. Unless there’s a real technical reason for the lack of an Android 4.0 upgrade—something Samsung should make clear—this might be the best answer. It wouldn’t cost nearly as much for Samsung to develop and test, while consumers thinking Samsung has let them down might be more accepting of the situation.

Ryan:  Samsung needs to seriously get their &%#* together.  I would like to update my Samsung Galaxy Tab, I find it buggy and it force closes way too much, too bad I will be forced to workaround this to put 4.0 on myself manually.

Bad products, horrible software and no cohesive vision have seemingly turned Research In Motion into a company without motion at this point.

Throw in a huge delay before BlackBerry 10 smartphones start shipping, and it’s clear why people are losing, or have lost, faith in a company that played a tremendous role in making the smartphone industry what it is today. Thanks to one of our most trusted sources, BGR now has new information on what’s going on inside Research In Motion, and the picture isn’t pretty.

Our source has communicated to us in no uncertain terms that PlayBook 2.0 — the next-gen tablet operating system RIM is developing — is a crystal clear window into the state of BlackBerry 10 on the upcoming smartphones RIM is building.

And the view is none too good.

“Email and PIM [is better] on an 8700 than it is on BlackBerry 10,” our contact said while talking to us about RIM’s failure to make the company’s upcoming smartphone OS work with the network infrastructure RIM is known for.

We also have more background on why RIM’s BlackBerry 10 smartphones are delayed, and it has nothing to do with a new chipset that RIM is waiting on. Our source told us that CEO Mike Lazaridis was lying when he said the company’s new lineup was delayed for that reason.

“RIM is simply pushing this out as long as they can for one reason, they don’t have a working product yet,” we were told.

At the end of our conversation, our source communicated something shocking for a high-level RIM employee to say. He told us that RIM is betting its business on a platform and ecosystem that isn’t even as good as iPhone OS 1.0 or Android 2.0. “There’s no room for a fourth ecosystem,” he stated.

Microsoft’s range of Windows Phone devices suffer from a denial-of-service attack that allows attackers to disable the messaging functionality on a device.

The flaw works simply by sending an SMS to a Windows Phone user. Windows Phone 7.5 devices will reboot and the messaging hub will not open despite repeat attempts. We have tested the attack on a range of Windows Phone devices, including HTC’s TITAN and Samsung’s Focus Flash. Some devices were running the 7740 version of Windows Phone 7.5, others were on Mango RTM build 7720. The attack is not device specific and appears to be an issue with the way the Windows Phone messaging hub handles messages. The bug is also triggered if a user sends a Facebook chat message or Windows Live Messenger message to a recipient.

The flaw appears to affect other aspects of the Windows Phone operating system too. If a user has pinned a friend as a live tile on their device and the friend posts a particular message on Facebook then the live tile will update and causes the device to lock up. Thankfully there’s a workaround for the live tile issue, at initial boot up you have a small amount of time to get past the lock screen and into the home screen to remove the pinned live tile before it flips over and locks the device.

Both Apple and Google have suffered from SMS bugs with their iOS and Android devices. Security researcher Charlie Miller discovered a flaw in the iOS 3.0 software that allowed attackers complete control over an iPhone at the time. Android-based phones also suffered in the SMS attack, but attackers could only knock a phone offline rather than gain full access. The attack described in this article does not appear to be security related. It appears, from our limited testing, that the bug is related to the way Windows Phone handles messages.

Khaled Salameh discovered the flaw and reported it to us on Monday. WinRumors is in the process of disclosing the bug directly to Microsoft privately in co-operation with Khaled. At this stage there doesn’t appear to be a workaround to fix the messaging hub apart from hard resetting and wiping the device. Please see the video below for a demonstration.

The tagline reads “enjoy your Android over the air,” but perhaps more accurate would be “enjoy your Android over your computer.” AirDroid connects your Android device to your desktop, laptop or tablet — really anything that can browse the web — and lets you send messages, browse photos or files, set ringtones, uninstall apps, and many other things that can be done more easily through a larger screen and perhaps a mouse and full-sized keyboard. If you want this type of functionality, don’t hesitate to download this free app.

I’ve used other apps that claim to provide the same or similar features, but this is the best that I’ve personally tried. It’s easy — just launch AirDroid and it shows a specific URL (IP address) to type in your browser and a password to keep it secure. It’s fast, too. Once your browser connects, just click through the big icons on the web page to navigate into picture and files, view the call log, read text messages, and a lot more in a second. It’s also secure. AirDroid doesn’t store any of your info on its systems, and the password changes with each use (or you can set your own password if you prefer). All this, and it’s 100 percent free.

Once you control your phone over a computer screen, you’ll want to do so every time you’re near a computer. It’s very convenient. The app works its magic over a Wi-Fi connection.

BlackBerry maker Research In Motion has allowed apps Google’s Android operating system to run on its BlackBerry Playbook tablet thanks to an emulator. Now it seems to want to return the favor by offering its software to Android and Apple’s iOS users.

According to a story from Ars Technica, RIM is offering its device management software to both its major competitors. The company made the announcement today that it would make the software available to Android and iPhone owners, which would allow users to manage those devices alongside BlackBerry devices using the software.

The new software is called BlackBerry Mobile Fusion and gives a lot of the same device management controls that BlackBerry customers enjoy (like remote phone locking and wiping and security features) to non-BlackBerry phones. It’s an acknowledgment on RIM’s part that it’s slowly losing its dominance in the field of business. While BlackBerry devices are still used heavily in enterprise, companies are also allowing employees to bring their own phones and use them.

BlackBerry Mobile Fusion allows RIM to continue to support its devices among businesses, even if its users also have other devices. RIM is aiming to become the “de facto platform” for device management among enterprise users, according to Alan Panezic, VP of enterprise product management at RIM. So while BlackBerry devices might be losing their market share, RIM doesn’t intend to be forgotten: it may just have to change the way it does things.

RIM has its work cut out for it, though. Its BlackBerry devices still curry a lot of favor among the government and businesses, but it’s losing traction to the widespread popularity of Android, and Apple’s iPad is popping up more and more in business settings. It probably didn’t help that BlackBerry devices suffered a worldwide outage in October. But the popularity BlackBerry does enjoy, as Ars Technica points out, largely comes from its management capabilities. Now Android users are going to have access to those same capabilities, which could help RIM maintain some popularity, especially if those capabilities become as popular on other devices as they have been on BlackBerrys.

On the other hand, if RIM gives up the things that make its handsets unique – by allowing millions upon millions of Android users to have those same capabilities without buying a BlackBerry – it could very well have a huge negative impact on the BlackBerry. We’ll have to wait and see if RIM’s gamble pays off, but in the meantime, Android users are going to have access to some potentially cool new software.

RIM says it’ll be releasing BlackBerry Mobile Fusion in the first quarter of 2012.

A computer with a wireless Internet connection hurts sperm, but not because the machine can heat up your lap, a new study suggests.

The findings showed that sperm cells collected in lab dishes and placed beneath a laptop with a wireless Internet connection for four hours had less motility and more DNA damage than sperm placed in another room, away from electronic devices but kept at the same temperature.

“It is well-known that increased temperature may decrease sperm quality, and the use of portable computers on the lap increases scrotal temperature,” the researchers wrote in their study.

But the findings suggested it wasn’t the temperature beneath the laptop that was affecting sperm; instead, the radiation from the laptop was slowing the swimmers, according to the study.

Laptops emit radiation

The researchers in Argentina and Virginia used semen samples from 29 healthy men, whose average age was 34. The laptop was set to download and upload information over the course of the experiment, so the wireless connection was actively being used. The temperature under the laptop was held constant at 77 degrees Fahrenheit by an air-conditioning system.

Wireless Internet connections use radio-frequency electromagnetic waves. When the researchers measured the radiation coming from a laptop wirelessly connected to the Internet, they found it was at least three times higher than an unconnected laptop, and seven to 15 times higher than radiation in a general setting, according to the study, though the levels varied over the course of the experiment, depending on the flow of information coming to or from the computer.

There was no difference between the sperm samples held under the laptop and those kept away from it in terms of the percentage of sperm that were dead at the end of the experiment, according to the study.

Still, sperm motility and having undamaged DNA are important for fertilizing an egg.

“We speculate that keeping a laptop connected wirelessly to the Internet on the lap near the testes may result in decreased male fertility,” the researchers wrote in their conclusion.

Why sperm cells are vulnerable

Sperm cells are different from other cells in the body — their DNA is highly condensed into a small area, the researchers noted. This could make them more vulnerable to the effects of such radiation.

It’s plausible that the magnetic and electromagnetic fields produced by the radio waves damage molecules in sperm called phospholipids, which are a needed to keep membranes within a sperm cell intact, the study researchers wrote.

It is not known whether all laptop computers might have the same effects as those seen in this study, nor is it known what other factors might heighten or lessen the damage, the researchers wrote in their conclusion.

“However, we cannot discard the possibility that damage to sperm is caused by the low radiation produced by the computer without Internet connection,” they wrote, and this possibility should be studied further.

The study was published online Nov. 23 in the journal Fertility and Sterility.

Pass it on: Radiation from wireless internet connections might damage sperm cells.

Summary: Now that Flash has had its day in the sun, the PlayBook may now have a chance to quietly sail off into the deathly sunset.

Research in Motion plans to continue supporting Adobe Flash, days after it emerged that the platform was not only on its last legs, but that it was to be taken round the back of the stable and beaten over the head with a rusty spade.

In a statement on the company’s corporate blog, the BlackBerry maker said:

“Earlier today, Adobe announced plans to stop investing in Flash® for mobile browsing, and focus more efforts on HTML5. As an Adobe source code licensee, we will continue to work on and release our own implementations, and are looking forward to including Flash 11.1 for the BlackBerry PlayBook.”

At roughly 10am this morning, a collective face-palm slapping sound was heard across the United States and Canada.

It is as though the BlackBerry maker is purposefully trying to continually do things to deliberately lower its stock price. I’m serious; is this some game show that I’m not aware of, where contenders win a vacation to the Bahamas if they successfully cripple their company within the space of a year?

The PlayBook has hardly been the most popular tablet the market has seen in recent years. In fact, come Christmas, I would place money that out of the ‘major players’, including Samsung, Motorola, and obviously Apple, that Research in Motion’s tablet will still come bottom of the pile.

But to continue to support an already dead platform on a dying tablet is like throwing salt in the wound of an already squashed slug.

It’s not the best analogy I should have come out with, but you get the idea.

Granted, the PlayBook does support HTML5, at least giving the tablet a break from a major software update that would be necessary to effectively replace the world’s most used web plug-in. It saves on a lot of headaches down the line, which from the perspective of future proofing was not a far off move.

The Ontario-based company will have the ability to continue to develop Flash on its own moving forward, keeping a ‘healthy’ following of developers interested and supported — that is, if you considered the aforementioned slug analogy to be healthy.

The PlayBook never really stood a chance, stood in line like the nerdy, glasses-wearing kid next to its prom-queen older sister. Even when the PlayBook had a chance to shine, in its secure emailing client that emulated the BlackBerry enterprise encryption, the tablet launched without it. In effect, its most favourable feature was left behind its launch.

But the linchpin to the PlayBook has always been its less than desirable advertising.

Nearly all of the company’s advertising and marketing efforts have been on the fact the PlayBook, unlike the iPad, as the supreme competitor to all other tablets on the market, will support Flash-based content. Though it still will, and Flash will not suddenly drop off the edge of the planet in the next few months, the BlackBerry maker is going to have to think of a brand new marketing strategy.

At least now Research in Motion can advertise the PlayBook as something it should have been marketed as a long way back: “The most expensive paperweight you never needed in the first place”.
