I spent time today playing with NextWorth, a Web site that will tell you the trade-in value of many electronic devices. The site covers everything from MP3 players to video games, but I went straight to cell phones, of course, to see how much I could round up for the handsets we have sitting around the CNET offices.

All you have to do is go to NextWorth's site and plug in the name of your device. You'll also have to answer a few questions such as if any parts of the handset are broken or water damaged, if … Read more

Losing a cell phone is never an ideal scenario, but Sprint is now offering smartphone customers an additional protective measure if their handsets go astray. Starting today, Android and BlackBerry users who sign up for the carrier's Total Equipment Protection plan not only can get a new phone, but also they'll be able to wipe their missing handsets.

The service, which will be included in the plan's $7-per-month charge, offers a number of features. Subscribers can back up and erase contacts on the lost device, remotely lock a smartphone, and track a device via GPS while seeing … Read more

Researchers at the University of Illinois may not be unveiling a major technological breakthrough, but their "Scientific Animations Without Borders" initiative could inspire a paradigm shift in the world of health and sustainable development education.

Currently, this kind of education outreach tends to be both expensive and time-consuming, with researchers often flying great distances for several weeks or months to teach, say, Haitians how to avoid cholera exposure, often with minimal follow-up.

So a team of extension educators in Champagne, Ill., is developing two-minute educational animations viewable on cell phones (see example here)--a tool that could save … Read more

The Android 2.3.3 update that began hitting Nexus S phones this week is notable not for what it provides, but for what it is not allowing.

Google is using the update to apply platform rules that were in place but not reinforced. In a nutshell, Google is restricting the official Facebook application from integrating its contacts with the Android Contacts application. As Google put it, consumers could be confused into thinking they can export these contacts should they decide to do so.

In the end, this move may go largely unnoticed as Google says only the Nexus S … Read more

A Web site and app out of Germany applies the wiki approach to maps, enabling users around the world to use the OpenStreetMap platform to rate and comment on the wheelchair accessibility of a wide range of establishments, from bars and shops to underground metro stops.

Called Wheelmap, the free app for iOS devices is in English, German, and Japanese, and while still in beta (version 1.1 adds Japanese), it already includes details on some 30,000 locations, with roughly 300 new user ratings every day.

Wheelmap is the brainchild of Raul Krauthausen, who wanted to create a service … Read more

Another Mobile World Congress is in the bag, and as the CNET crew leaves Barcelona we can take stock of the mobile madness that was. It was my fourth year attending the show, and I can report that 2011 was one the busiest I've seen, with a ton of new smartphones and tablets. It was a lot to handle, but Bonnie Cha of CNET Reviews; Ariel Nunez of CNET TV; and Maggie Reardon, Stephen Shankland, and Elinor Mills of CNET News were along for the ride.

As with any trade show, Mobile World Congress offered a series of satisfying devices and a couple of instances where companies fell short. Here's the report from Barcelona as we saw it. And don't forget to check out Maggie's insights in her Ask Maggie column. … Read more

The big industry event about virtualization is VMworld, usually held in late Summer / early Fall. You don't have to wait for VMware's conference, however, to find yourself in VM World. We now live in it, every day.

It's really quite amazing how quickly virtualization has swept through, and become ensconced in, IT. Data centers have--for decades--been famously conservative when it comes to introducing changes that might threaten to disrupt production applications. For years, whenever we'd ask operationally focused IT managers about introducing new control software--for workload management, service provisioning, automated orchestration, and so on--we always heard … Read more

BARCELONA, Spain--Later this year you'll be able to pay for clothes, taxi fare, and dinner with your mobile phone and leave your credit cards and cash at home.

Visa is planning a commercial rollout in the U.S. in the second half of this year of a service for allowing allow people to turn their existing smartphones into electronic wallets. It uses Near Field Communication (NFC) short-range wireless technology and includes real-time anti-fraud alerts and other features designed to protect consumers from fraud, Bill Gajda, global head of Visa Mobile, told CNET in an interview at Mobile World Congress 2011 … Read more
