All of the rumours up until now have pointed to AT&T as being the US carrier for the Sony Ericsson Xperia X10. A trusted source of Engadget has also heard the same, giving some launch information along the way.
The source suggests that the Xperia X10 will land at AT&T during fiscal week 30 of 2010, placing the launch at the end of July/beginning of August. Hopefully, we’ll hear some kind of confirmation from AT&T on this news shortly.
Obviously, all of this is subject to change, but I do wonder whether AT&T would launch the device with Android 1.6. Previous rumours suggested that the X10 may launch in the US with the latest Android release.
