Experiences with wireless carriers in the United States seem heavily dependent on location and personal travel routes, which is why anecdotal evidence about coverage is generally not very useful. Comparing their coverage maps, it looks clear that AT&T technically has more network coverage: AT&T: http://www.wireless.att.com/coverageviewer/#?type=voice http://www.wireless.att.com/coverageviewer/#?type=voice T-Mobile: http://www.t-mobile.com/coverage/pcc.aspx http://www.t-mobile.com/coverage/pcc.aspx If I lived in an urban area (where T-Mobile is likely to have already deployed both standard 3G and HSDPA+ coverage, and AT&T's network has a higher than average proportion of heavy iPhone users), my experiences with either carrier are likely to be different than if I lived and stayed in the suburbs or rural areas (where T-Mobile is more likely to either have EDGE coverage or nothing at all).
