It looks like the Motorola xt701 (Sholes tablet) is being sold "unlocked" at amazon and newegg ($449 at newegg) and supports AT&T 3G bands. I had always thought this was Chinese-only, and since many people on AT&T were looking for a decent Android device, did this one kind of slip under the radar? Maybe a good alternative, if the Captivate isn't cutting it for some? My hesitation with the Captivate is the lack of a flash (light), and somewhat low call volume levels. Lacking the AT&T software may also be a draw for some.
