Looks like the Sony Ericsson might finally land a smartphone on a U.S. carrier. Engadget Mobile says they have it from a trusted source that the Xperia X10 is slated for release in the 30th fiscal week of the year, which would put it at the tail end of July or the first week of August. And remember that the review units that are making the rounds have AT&T’s 3G bands, so it’s not that far-fetched. That said, we can’t help buy wonder what kind of horrible things AT&T may have in store for the X10. Stay tuned. [Engadget Mobile]
