BARCELONA, MOBILE WORLD CONGRESS — Thanks to the original PadFone’s rather disappointing start, we thought the probability of seeing a successor at Mobile World Congress was slim at best. But we couldn’t be more wrong. Asus has just unveiled the PadFone Infinity, a 5-inch smartphone that transforms into a 10.1-inch tablet with the help of a clever docking station.

The device has some impressive specifications, including a 1080p display, a quad-core Snapdragon 600 processor, and a 13-megapixel camera. But do you really want a smartphone that transforms into a tablet? We went hands-on with the device to find out.

BARCELONA, MOBILE WORLD CONGRESS — The Huawei Ascend P2 has appeared in a number of leaked photos in previous weeks, but at Mobile World Congress in Barcelona today, the device finally got its official unveiling. I got my mitts on the device as soon as I spotted it, and I was instantly impressed. Here’s why.

BARCELONA, MOBILE WORLD CONGRESS — As I was walking around the show floor at MWC today, I noticed a number of smartphones that looked very familiar — yet they were being paraded by Chinese companies I’d never heard of. I saw what looked like a large iPhone 5, an entire range of Samsung Galaxy devices, and a number of high-end HTC handsets.

Except they weren’t really Apple, Samsung, or HTC devices at all; they were actually cheap clones that were trying their best to look like the real thing. They even had fake accessories that were identical to the originals.

BARCELONA, MOBILE WORLD CONGRESS — Here at MWC, ZTE has announced that it will be launching the world’s first commercially available Firefox OS smartphone this summer. Called the ZTE Open, the entry-level device is the first of a series of Open smartphones coming from the Chinese company, and it’s aimed at consumers who want to “ experience the latest technology on a limited budget.”

If you were expecting Samsung to unveil the Galaxy S4 at Mobile World Congress in Barcelona this week, prepare to be disappointed: Samsung has instead sent out invitations to a press event in New York on March 14, where they will debut their much-anticipated (and iPhone 5 challenging) new smartphone.
