T-Mobile apparently just confirmed an April 24 availability date for the HTC One smartphone. Rather than through a formal press release, the carrier confirmed when HTC's hot flagship handset will grace its shelves via a short and sweet Twitter update.

According to T-Mobile watcher TmoNews, the wireless company tweeted the info tidbit through its T-Mobile USA account. The announcement specifically calls out the LTE version of the HTC One, which should come as no surprise since it was one of the devices highlighted at the carrier's recent LTE unveiling in New York.

There's been a lot of … Read more

Don't want to wait for the Samsung Galaxy S4 to hit stores? Then perhaps you'll be tempted by a new purple-hued version of Samsung's hit handset from last year, the Galaxy S3. Sprint announced it will sell a special Amethyst Purple GS3, as well as the older Pebble Blue and Marble White models, for $99.99.

Of course that discount applies only to customers who bring their service and phone number from other carriers, or existing subscribers who add another line. That lops $99.99 off the Galaxy S3's unsubsidized $549.99 price. You also have … Read more

You may eventually be able to transfer files between a computer and mobile device just by placing the two near each other.

Published today by the U.S. Patent and Trademark Office, an Apple patent application known as "Apparatus and method for interacting with handheld carrier hosting media content," describes a file transfer technology that automatically kicks in when two devices are positioned next to each other. One device would sense when the other is nearby and then send or receive a certain document, picture, song, or other item.

As one example, you may be creating an e-mail … Read more

Waiting on hold may not be so dull if a newly patented Apple technology ever ends up a reality.

Granted to Apple today by the U.S. Patent and Trademark Office, a patent called "Communications system that provides user-selectable data when user is on-hold" envisions a system for showing useful and interesting information to mobile phone callers waiting on hold.

The information being displayed would be adaptive and contextual, according to the patent, meaning it would vary depending on the caller, the caller's location, the date and time, and other items. As one example, the caller might … Read more

Today, T-Mobile hyped how much easier bringing phones to its new network will be. As it turns out, however, it isn't as simple as you'd think.

Here's the deal. T-Mobile is in the middle of three major wireless transitions. Besides ripping up mandatory two-year contracts, the carrier is building a new 4G LTE network. If that wasn't enough, T-Mobile also is migrating its older 3.5G data service from the AWS band (1700/2100) where it currently lives over to the 1,900MHz GSM band.

But that's not all. T-Mobile is using that freed-up AWS … Read more

T-Mobile's new service plans mark a huge change for wireless carriers. In addition to ditching contracts, the nation's fourth largest wireless provider also has dropped handset subsidies completely. So now, when you buy a new phone from T-Mobile, you'll pay much more for your device than you did when you signed two years of your life away. You have the option of paying the full cost at the time of purchase, or paying a deposit with monthly installments, but the phone's price is the same either way. And, of course, you won't be tied to … Read more

T-Mobile just took a bold, new step by shredding the contracts for its plans plus launching its new 4G LTE data network. But what kind of speeds can you really expect to see on the carrier's hot, new devices? Judging from what I observed at T-Mobile's splashy press event in New York, apparently quite a bit. … Read more

If researchers at the University of California at San Francisco have their way, their new heart disease study won't suffer from a small sample size. Using online and mobile phone tools, they hope to get 1 million people from around the world to participate.

Launched this week, their Health eHeart Study (yes, very cute) enables participants to use their smartphones to frequently monitor heart rate, blood pressure, and pulse rate, and submit the resulting data via a secure online portal. The researchers, in turn, will use fancy algorithms to crunch that massive volume of data.

The goal? To use the super sample size to better understand -- and thus predict and prevent -- heart disease.… Read more
