As I write this, CNET writers from three countries are traveling to Barcelona, Spain, to bring you the best of the annual Mobile World Congress trade show.

If you're a smartphone fan, you probably know that Mobile World Congress (MWC) is a big deal. And if you don't know about it but still love gadgets and technology, there are very good reasons why you should care. I'll explain.

To put it simply, MWC is the most important wireless trade show of the year. It's bigger than CES (where, no … Read more

The Federal Communications Commission yesterday announced new regulations for cell phone signal boosters.

Under the new rules, anyone who has a signal booster or plans to buy one must obtain permission to use it from their carrier. If permission is obtained, the signal booster must be registered with the carrier to ensure it meets specifications and all parties are aware of its use.

The FCC's rules, which were first brought to the floor in 2011, take aim at reducing interference with wireless networks. Signal boosters are designed to connect to cell phones to improve a connection with towers in … Read more

The burden of being a teen never lightens. You think you've got studying cracked, when along comes dating. You think you've got dating cracked, when along come drugs.

And then there are music and clothes and gadgets to deal with. It's too much.

This might (or might not) offer some explanation as to why teens have started texting in their sleep. Yes, it's just like sleepwalking, except you can be really, really mean. LOL.… Read more

If there's one smartphone that looks like it could challenge the Samsung Galaxy S3's supremacy, it's the HTC Droid DNA.

CNET's Brian Bennett called it "the best phone I've seen from HTC in a long while, especially on Verizon," and a "better buy" than both the S3 and Motorola Droid Razr HD.

But the $199.99 Verizon charges for it (with a two-year contract, natch)? Ouch. Thankfully, there's a deal to be had: for a limited time, Wirefly has the HTC Droid DNA for $49.99 shipped. That's for … Read more

Selecting a wireless carrier is just as important as picking a phone. The provider, after all, delivers the network that makes your handset work. And since you'll probably end up paying a healthy amount for that privilege, there's no point in sticking with a bad user experience.

Fortunately, CNET is here to help guide you through the decision process. Read on for the major factors that you should consider when choosing a carrier, followed by brief descriptions of each of the major players that CNET reviews. Also, be sure to consult CNET's cell phone buying guide if … Read more

It costs me around $80 per month to operate my iPhone 4S, which will soon be out of contract.

When that joyous day comes, I will very likely ditch AT&T in favor of something like Solavei, one of a growing number of companies offering cheaper, no-contract mobile service.

Specifically, Solavei gives you unlimited voice, text, and 4G data for $49 per month. OK, there's an asterisk next to "unlimited": the 4G data bounty ends at 4GB, after which Solavei throttles you back to 2G-level service. More on that in a bit.

Unlike Walmart's AT&… Read more

Consumers will eventually pay less for entertainment streamed to smaller devices, with studios and distributors basing prices on the size of the destination device, movie mogul Jeffrey Katzenberg predicted today.

A tiered pricing market, in which people paid less to see a movie on a cell phone than a theater, would result in greater consumption in developing markets where people depend more on their mobile devices for entertainment, the DreamWorks Animation SKG chief executive said today at the Founders Forum conference on digital media in Los Angeles.

"People will pay by the square inch," Katzenberg said, according to … Read more

Some day in the future, when you need a kidney transplant, you may get a 3D-printed organ created just for you. If scientists are able to achieve that milestone, they may look back fondly at a breakthrough printing process pioneered by researchers at Heriot-Watt University in Scotland in collaboration with Roslin Cellab, a stem cell technology company.

The printer creates 3D spheroids using delicate embryonic cell cultures floating in a "bio ink" medium. They end up looking like little bubbles. Each droplet can contain as few as five stem cells. Basically, this comes down to the printer "ink" being stem cells rather than plastic or another material. … Read more

When I hear that Kim Jong-un, North Korea's "supreme leader," has released a little movie about a missile attack on the U.S., one thought enters my head: I wonder what sort of phone he has.

There is a part of me that believes he must be sporting a flip phone, in order to show solidarity with his fellow people, most of whom couldn't afford a flipped pancake, never mind a phone.

Yet TechInAsia offered me the startling news this morning that the man who is often portrayed with a cigarette in his hand -- like … Read more
