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.

Google began rolling out its Android 4.2.2 Jelly Bean update earlier this week, and it looked as though the software would bring nothing more than a few important bug fixes. But after used their devices after upgrading, Nexus owners have begun to notice some changes throughout the OS.

In addition to better download notifications, Android 4.2.2 brings some changes to the Quick Settings pane, and a number of new notification sounds.
