The radio just doesn't run those freqs for that protocol. AFAIK, Edge should be good. This has been the case with iPhones for a while, but I don't know if that changed with the 4S and beyond. For a long time, unlocking AT&T iPhones and selling to T-Mo subscribers has had to come with the caveat that the T-Mo guy can't use 3G.

The iP4 does have HSPA (3.5G) capability at 2100 though. So if you're in a 2100 area, you should be good for UMTS. Otherwise, I think you might be stuck with Edge.
Too bad EDGE is total crap.
