Many posts say 'You need an 850 phone for AT&T' - but it's often not clear whether that's for GSM (2G) or UMTS.

I found this site
WirelessAdvisor
which tells you (IIUC) who licenses the spectrum where. Plugging in a random place in Virgina: Shanadoah tells me that AT&T use UMTS 850. Or does it?

I assume that all US phones have 850 and 1900 - it seems odd that this one only has 850 if that's an unusual frequency. Maybe I'll try emailing AT&T.

@Photojim: thanks for the comment about prepaid - I would not have guessed that it matters. AT&T prepaid (aka Gophone?) reception seems OK in the area I mentioned in my OP. The phone does have EDGE.
