Mobile World Congress isn't just about introducing new cell phones. No, the world's largest wireless show in Barcelona, Spain, also is about showing off the latest mobile technologies that may or may not change your life.

Take, for example, NFC or near field communications. Not only did many of the new devices unveiled at the show come NFC-capable, but also the NFC Cafe displayed a gallery of solutions for mobile payments technology.

Making a purchase is a prime example, of course, but NFC also can be used to secure your motorcycle, navigate your way through an unfamiliar subway … Read more

In addition to the LG Viper due out this spring, Sprint plans to add Google Wallet to nine other phones within the year.

The wireless payment service that lets you pay for items with your phone through an NFC chip, is currently available on only two phones: the Nexus S and Galaxy Nexus.

According to Fierce Mobile Content, Vice President of Google Wallet and Payments Osama Bedier said that Google will continue talking to other operators, manufacturers, and financial institutions to expand the Wallet's reach.

CNET's own Marguerite Reardon remains skeptical of the money service, given that it'… Read more

In an effort to quickly and efficiently map the roughly 5,000 automated external defibrillators (AEDs) in public areas of Philadelphia, researchers at the University of Pennsylvania's Perelman School of Medicine recently launched a contest to award $10,000 to the team or person who finds the most.

With the six-week contest, which kicked off in late January, nearing its March 13 deadline, researchers are already planning to conduct a similar, nationwide challenge.

AEDs can save the lives of those suffering cardiac arrests via electric shocks, particularly if used in the first minutes following the onset of the attack. … Read more

Apparently, new phones, tablets, and other hardware aren't making the only news coming out of Barcelona, Spain, this week, as popular social discovery engine StumbleUpon has just released its newest Android app.

A featured developer at the Google Android booth, StumbleUpon got to show off its updated Android app as well as its new logo and color scheme at Mobile World Congress.

If you're not familiar with StumbleUpon, it's basically a Web site that helps you discover new Web sites. It gets to know you through your profile and your Web browsing activity, then uses the data … Read more

BARCELONA, Spain--Even with some significant engine trouble, it took me a day to go from zero to addicted to XCom Global's MiFi rental service for travelers.

TheInter Communications subsidiary offers a handy service--$14.95 a day to rent a mobile MiFi network access point with unlimited data access when you're traveling abroad.

The price looks painful until you compare it to the alternative: I just paid my French carrier, SFR, a whopping 19 euros (more than $25) for a measly 40MB of data while I'm at the Mobile World Congress show here. And carrier gouging isn'… Read more

AT&T is making two announcements in conjunction with the upcoming Mobile World Congress in Barcelona that could help consumers reduce their environmental footprints.

First, the company is announcing a new remote monitoring platform that will ultimately allow users to remotely and automatically adjust energy usage in their homes. The service and technology is being developed for international carriers, who can then develop and sell energy conserving services around the world. The service platform will also allow carriers to offer home security services too.

AT&T is calling the new platform Digital Life. The system, which can be … Read more

It's no secret SMS is wildly popular, but according to a new report from research firm Ovum, carriers around the world lost quite a bit of revenue last year after mobile phone owners turned to other services to chat with friends.

The research firm revealed yesterday that carriers lost $13.9 billion in SMS revenue in 2011 because of consumers chatting with friends on social-messaging applications. Those applications range from everything from Facebook's mobile app, which features chatting, to instant-messaging apps. Apple's iMessage is also included in that list.

It was a similarly disappointing year for carriers … Read more

Most of us have at least tried to text without looking at our phones before. I confess to having shot off a quick message while stopped at a red light, or immediately following crazy goals and tackles at soccer matches, or even from the confines of my pocket at parties.

Now a free, open-source app called BrailleTouch is about to make this form of multitasking that much easier--for the visually impaired and sighted alike.

Designed at Georgia Tech, the app incorporates the Braille writing system into a touch-screen device. It essentially turns an iPhone's touch screen into a soft-touch … Read more

If you're wondering whether you're too many cups or too many hours into the day for yet another jolt of caffeine, a free app developed by researchers at Pennsylvania State University aims to help.

In building the Caffeine Zone app, professors representing several disciplines relied on peer-reviewed studies to devise a simple formula: those with between 200 and 400 milligrams of caffeine in their bloodstream are in the optimal mental alertness zone, while anyone above 100 milligrams has entered the good-luck-sleeping-anytime-soon zone.

"Many people don't understand how caffeine levels in their bloodstream go up and how … Read more
