BARCELONA, MOBILE WORLD CONGRESS — During a Samsung developer conference here at Mobile World Congress this morning, the Korean company unveiled a new service called Samsung Wallet, which lets Samsung smartphone owners turn tickets, coupons, membership cards, boarding passes, and more into digital cards that they can store in a virtual wallet.

The service probably sounds familiar, and it is — Samsung Wallet is basically Apple’s Passbook, but for Samsung phones. It works in almost exactly the same way, and looks very similar, too.

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 — Here at Mobile World Congress, ZTE is showing off the Grand Memo, its new super-sized smartphone that packs a giant 5.7-inch display. That’s 0.2 inches bigger than the Galaxy Note II’s display, and although that doesn’t sound much, it’s instantly recognizable when you pick up this handset for the first time.

Sony has confirmed that its entry-level Xperia E Dual is making its way to the United States. The $199 device, which offers a 3.5-inch scratch-resistant display and dual-SIM functionality, will be shipping from March 3. Sony has begun accepting orders for the device via its online store.
