I've seen a few threads with various answers to this question. Some say that the Blaze T769 from T-mobile works fine on AT&T's network with speeds of 3-5 mpbs. Others say they can only get 2G speeds. I would like to use the Blaze on AT&T's network and want to be sure of what speeds I'll get.
Based on specs, it looks like I should get coverage on everything but AT&T's 700MHz band, but I'm not that savvy on this technology, so I don't know what other issues there may be. What can I expect?
