I'm in an area that has great T-Mobile voice coverage, but data leaves something to be desired. I went ahead with the G1 despite this. I've been fairly satisfied with the speed I have for IM, E-mail, D/L Apps, and general browsing, just Youtube app sucks. Does anybody know how I can figure out what areas near me offer EDGE? My coverage map merges EDGE/GPRS into one coverage area.
