If you bought a phone at a SonyStyle store last year, it was most likely a Sony Ericsson Xperia phone. The Xperia name is trying to join the ranks of Evo, Droid, and Razr in the world of high-value Android brands. Later this month, we'll see a whole new slate of Sony Xperia devices when they're on display at the Mobile World Congress in Spain. Wait; did you catch the big difference in what we just wrote? It's "Sony Xperia," not "Sony Ericsson Xperia."
