Debuting at Mobile World Congress, the LG Optimus G Pro is a 5.5-inch device that will launch in Korea this month, followed by a North American release in Q2. The handset is actually LG's third crack at the phone/tablet hybrid niche, after its Optimus Vu and Vu II (the U.S. carrier, Verizon, released the former as the LG Intuition, which received a lukewarm response).

But this phone is more than just another attempt; it shows how the third time can indeed be a charm. Not only does it boast powerful quad-core specs, it also features the … Read more

Google appears eager to let other organizations use certain top-level domains that it wants to acquire and manage.

Last June, the Internet Corporation for Assigned Named and Numbers (ICANN) revealed which companies and organizations had applied for their own generic top-level domains (gTLDs). The effort is part of a move to foster competition on the Internet by allowing companies to use a greater variety of TLDs beyond just .com.

Google applied for 101 of the 1,900 available gTLDs, looking to score such obvious ones as .google, .chrome, .gmail, .goog, and .youtube. But along with those gTLDs were ones that … Read more

Amazon's effort to control dozens of new generic top-level Internet domain names is drawing fire from a pair of publishing industry groups.

The Authors Guild and the Association of American Publishers oppose the Internet retail giant's plan to control so-called generic top-level domains (gTLD) that end in suffixes .book, .author, and .read, arguing that such influence would be anti-competitive.

"Placing such generic domains in private hands is plainly anticompetitive, allowing already dominant, well-capitalized companies to expand and entrench their market power," Authors Guild President Scott Turow wrote to the Internet Corporation for Assigned Names and Numbers, … Read more

I'm a big believer in the old Boy Scout motto: be prepared.

That's why I always pack a prepaid modem in my travel bag, just in case there's no Wi-Fi available wherever I end up. This happens more often than you might think.

Through tomorrow, and while supplies last, you can get the T-Mobile Jet 2.0 prepaid 4G laptop stick for $19.99 shipped. Props to reader Harvey for sharing this deal.

Like the aircards of old, the Jet 2.0 plugs into your Mac or PC, endowing it with high-speed Internet access -- in this … Read more

BARCELONA, Spain--Here's the good news: the U.S. wireless industry is working to ensure that you'll eventually be able to take your LTE-enabled phone from one carrier to another and get the same experience.

The bad news: it likely won't happen for a few years.

That's according to T-Mobile Chief Technology Officer Neville Ray, who spoke to CNET in an interview at Mobile World Congress. Ray says the industry is keen on phones that can operate on different carriers, but that there remain a lot of complexities.

The advent of 4G LTE technology was supposed to … Read more
