Before you recycle your old computer, cell phone or smart phone, make sure that you wipe it clean of data. If you don't, your personal life could be laid bare. Worse, you could become a victim of identity theft.
But wiping your device clean of data may be harder than you think. Here are details about how to do it for cell phones and PCs.

Cleaning up cell phones and smart phones
With cell phones and smart phones like BlackBerries, you need to worry about more than your data -- make sure that your account has been terminated. If not, others will be able to make phone calls from your device, and you'll be footing the bill. So double-check with your carrier that the account has been terminated before you donate or sell your phone. If you've switched your account over to a new device and deactivated the old device on that account, check your bill carefully to make sure that the old phone isn't somehow still using that account.
Next, erase all of your stored information, including your phone book, any stored incoming or outgoing text messages, and memory of incoming and outgoing phone numbers, e-mails and so on. You can do this manually, one by one, of course, but if you do, there's a good chance you might miss some. And it can also be exceedingly time-consuming. So check your phone's manual for how to do a complete reset. A reset will wipe your phone of data and restore it to its factory settings.
A superb resource for figuring out how to reset cell phone data is put together by ReCellular, which buys, recycles and refurbishes wireless devices. Its cell phone data eraser site gives detailed instructions on how to erase data from many different makes and models of cell phones. Just choose your make and model, and you'll be able to download specific instructions for resetting it.

Wiping PCs
Just deleting files isn't good enough when you are going to recycle your computer. It's quite simple for anyone to restore those deleted files, even if they're no longer in the Recycle Bin. In fact, even deleting files and reformatting your hard disk won't completely do the trick. Someone knowledgeable enough and dedicated to the task will be able to restore your files, even from a reformatted disk.
Think there's nothing to worry about? You couldn't be more wrong. In 2003, two graduate students at MIT's Laboratory for Computer Science bought 158 used hard disks on eBay and other places. From those hard disks, they were able to discover 5,000 credit card numbers, personal and corporate financial records, medical records and personal e-mails.
Only 12 of the 158 hard disks had been properly cleaned of their data. Approximately 60% of the hard drives had been reformatted, and about 45% of the drives had no files on them (the drives couldn't even be mounted on a computer) -- yet the students were still able to recover data from them, using a variety of special tools. For details, see the news story from MIT.
What can you do? Get a disk-wiping program, preferably one that meets the U.S. Department of Defense's standards for disk sanitation. These programs will overwrite your entire hard disk with data multiple times, ensuring that the original data can't be retrieved. If you use them, be patient, because it can take several hours to wipe the hard disk.
Computerworld features editor Valerie Potter vouches for the free Darik's Boot and Nuke, which, unlike some competing programs, worked smoothly on the old Windows 98 machine that she recently put out to pasture. Download the software, which then creates a boot disk that wipes everything on the hard drive. It can be used with floppy disks (remember those?), USB flash drives, CDs and DVDs. A similar program that has gotten good reviews is Eraser.
If you've got a Mac, you can use Apple's built-in Disk Utility or download a third-party application like Mireth Technology's ShredIt X 5.8 ($25, free trial), which lets you shred single files as well as wipe your local hard drive, network hard drives and CD-RWs.
Everything clean? OK, now it's time to sell, donate or recycle your equipment. Find out what to do in "Out with the old: What to do with your unwanted tech gear."

Steve Jobs announced an iPhone SDK today. The plan is to release it in February, and the suggestion is that apps will need to be digitally signed (not unlike digital signing in Leopard). Here's hoping that developing for the iPhone/Touch will be cheap (or free) enough to allow the folks who have been writing apps to continue doing so. Says Jobs: 'It will take until February to release an SDK because we're trying to do two diametrically opposed things at once--provide an advanced and open platform to developers while at the same time protect iPhone users from viruses, malware, privacy attacks, etc. This is no easy task.'

Suffering from its exorbitant price point and a dearth of titles, Sony's PlayStation 3 isn't exactly the most popular gaming platform on the block. But while the console flounders in the commercial space, the PS3 may be finding a new calling in the realm of science and research. Right now, a cluster of eight interlinked PS3s is busy solving a celestial mystery involving gravitational waves and what happens when a super-massive black hole, about a million times the mass of our own sun, swallows up a star. As the architect of this research, Dr. Gaurav Khanna is employing his so-called "gravity grid" of PS3s to help measure these theoretical gravity waves -- ripples in space-time that travel at the speed of light -- that Einstein's Theory of Relativity predicted would emerge when such an event takes place. It turns out that the PS3 is ideal for doing precisely the kind of heavy computational lifting Khanna requires for his project, and the fact that it's a relatively open platform makes programming scientific applications feasible.
"The interest in the PS3 really was for two main reasons," explains Khanna, an assistant professor at the University of Massachusetts, Dartmouth who specializes in computational astrophysics. "One of those is that Sony did this remarkable thing of making the PS3 an open platform, so you can in fact run Linux on it and it doesn't control what you do."
He also says that the console's Cell processor, co-developed by Sony, IBM and Toshiba, can deliver massive amounts of power, comparable even to that of a supercomputer -- if you know how to optimize code and have a few extra consoles lying around that you can string together.
"The PS3/Linux combination offers a very attractive cost-performance solution whether the PS3s are distributed (like Sony and Stanford's http://folding.stanford.edu/) or clustered together (like Khanna's), says Sony's senior development manager of research and development, Noam Rimon.
According to Rimon, the Cell processor was designed as a parallel processing device, so he's not all that surprised the research community has embraced it. "It has a general purpose processor, as well as eight additional processing cores, each of which has two processing pipelines and can process multiple numbers, all at the same time," Rimon says.
This is precisely what Khanna needed. Prior to obtaining his PS3s, Khanna relied on grants from the National Science Foundation (NSF) to use various supercomputing sites spread across the United States "Typically I'd use a couple hundred processors -- going up to 500 -- to do these same types of things."
However, each of those supercomputer runs cost Khanna as much as $5,000 in grant money. Eight 60 GB PS3s would cost just $3,200, by contrast, but Khanna figured he would have a hard time convincing the NSF to give him a grant to buy game consoles, even if the overall price tag was lower. So after tweaking his code this past summer so that it could take advantage of the Cell's unique architecture, Khanna set about petitioning Sony for some help in the form of free PS3s.
"Once I was able to get to the point that I had this kind of performance from a single PS3, I think that's when Sony started paying attention," Khanna says of his optimized code.
Khanna says that his gravity grid has been up and running for a little over a month now and that, crudely speaking, his eight consoles are equal to about 200 of the supercomputing nodes he used to rely on.
"Basically, it's almost like a replacement," he says. "I don't have to use that supercomputer anymore, which is a good thing."
"For the same amount of money -- well, I didn't pay for it, but even if you look into the amount of funding that would go into buying something like eight PS3s -- for the same amount of money I can do these runs indefinitely."
The point of the simulations Khanna and his team at UMass are running on the cluster is to see if gravitational waves, which have been postulated for almost 100 years but have never been observed, are strong enough that we could actually observe them one day. Indeed, with NASA and other agencies building some very big gravitational wave observatories with the sensitivity to be able to detect these waves, Khanna's sees his work as complementary to such endeavors.

According to sources at a Taiwanese manufacturer, Google will definitely be launching its own branded phone. An article at DigiTimes states that the company has yet to finalize the handset's specifications, OS, production contractor and operating partners. 'TI's handset chipsets will find their way into the Google phone should the company decide to roll out an EDGE-compliant handset, but Qualcomm could turn out to be the winner if Google decides to bet on a 3G model ... However, the choice of a 3G platform might force Google to postpone the launch of the so-called Gphone to the first half of 2008 instead of the latter half of this year as expected due to the change of platform and problems related to licensing of patented technologies.

Intel and others plan to release a new version of the ubiquitous Universal Serial Bus technology in the first half of 2008, a revamp the chipmaker said will make data transfer rates more than 10 times as fast by adding fiber-optic links alongside the traditional copper wires." "The current USB 2.0 version has a top data-transfer rate of 480 megabits per second, so a tenfold increase would be 4.8 gigabits per second." This should make USB hard drives easier and faster to use."

CNN reports details of a group of anonymous programmers who are lanning to sell iPhone unlocking software on the Internet. They emonstrated the software hack for CNN and had a T-mobile sim card working moments after removing the AT&T sim card. This is bound to stir up a lot of controversy: in the US iPhones are supposed to work only on the AT&T network in the first two years according to their agreement with Apple.
