According to Engadget Mobile it is! Looks like AT&T is a natural fit for this in the U.S. Could be my new backup Blackberry, perfectly complimenting the Bold. I was scouting around for a reasonably priced current model, unlocked, and haven't found one I thought was worth it. Glad I waited!
I hope this is true.....my contract expires later this year AND my phone (first gen Pearl) is pretty much dying. Time for a new one, and I'd likely get Pearl flip.
