Sony Ericsson Xperia X10

Although Sony got a little ahead of themselves with the previous announcement of Gingerbread rolling out for the Sony Ericsson Xperia X10, they've gotten things back on track. Some of the first users getting the update notifications will be unbranded devices with carrier branded devices shortly following after. Once you get the update notification, you'll need to load up the PC Companion app in order to download and install Gingerbread but after that -- you'll be golden.
