And sure enough, the Sony Ericsson Xperia X10 is on its way to AT&T. ...
The 4-inch phone is bringing its custom Android experience to the U.S.
on Aug. 15, complete with 8-megapixel camera, LED flash, 8GB of on-board
memory, 2GB microSD card, and the Timescape and Mediascape UIs.

The X10 will cost $149.99 after two-year contract and rebate.
Off-contract pricing wasn't initially announced.

Also not announced was what version of Android will be on board at
launch, though we have to assume it'll be the same Android 1.6 that
we've previously seen, and hope that it'll be upgraded later this year.
