I got my iPhone 5 yesterday after several issues (that's another story). In case you need to know, it's a white 16GB. I have AT&T, and it has worked well for me in the past. It worked perfectly on my iPhone 4. WiFi is working very well, no problems with that. I have great cellular coverage (usually 4 or 5 bars). I noticed that I'm not getting any 4G, 3G, or even EDGE on my iPhone. Data is not working at all on my phone. I checked my settings and it says Cellular Data is ON. Should I call AT&T? Also, if so, who can call? My dad lives 3000 miles away, and I'm on his plan but I live with my mom. Would I have to make my dad call them?
