I thought I read that a couple of phones which came out recently weren't locked and was hoping maybe this one was cheap enough that they wouldn't bother.
Yes AT&T is supposed to get it later this summer but by then (and depending on the price), it might be too close to the McLaren release to waste the money. Meanwhile I just picked up a 520, applied the Preview for Developers and is probably close enough to the 635 to get me by.
