Sony Ericsson confirmed in a blog post on Monday that its developers have been working hard on the Android 2.3 Gingerbread update for the Xperia X10, and that the roll-out will begin in early August. The company confirmed that it will keep the original camera UI as found in the Eclair version of the phone, and that the Facebook Inside Xperia functionality in the newest Xperia family of phones will be available on the X10 as well. Unfortunately, SE said that it will not add DLNA support to the X10, as adding that would “jeopardize the time schedule.” Generic trade phones will get the Gingebread upgrade, which was announced in March, but Sony Ericsson did note that “some of you will not be able to upgrade your customized version of Xperia X10.” In other words, we seriously doubt AT&T users will ever get it.
