Both Edge and 3G signal strength is generall poor and the strength varies wildly, from "No service" to 3 bars and back in a just a few seconds sometimes. When we tested witha Motorola RAZR 3 before switching, service was great. We had T-Moble for 7 years before but left because of service being horrible, dropped calls, missed calls. Friends with Verizon only show 1 to 2 bars here also. We are in the shadow of the CAP canal levee, not sure if that makes a difference or not as a we see towers on top of the McDowell mountains close to us. Trying a repeater / antenna to see if that will help - its expensive though - considering you are already paying for the service.

Found out after purchasing the iPhone that there's extremely spotty service at my house. This happened a year ago with Verizon and it was remedied, but we need AT&T to step it up now that lots of people have their service due to the iPhone.

receive voice messages 20 minutes later..always dropped calls... ... ... turn your head and you are dropped!... use a blue tooth to try and not loose the call!... ..cellular sucks!

Everyone with T-Mobile laughs about how all the other carriers have great service in this location, but we have none!

Usually no reception in office bldg. Same with previous Samsung.

Sprint is Awful near old town and the civic center. Stay Away!

Good reception at out house and in DC Ranch and Grayhawk area, a little spotty around ice rink and McDowell Mtn Ranch where we used to live. Much better reception than guests at our house who had AT&T or Verizon.

Fluctuates between 1 and 2 bars. However call quality isn't effected.

No reception or signal indoors. Must stand in backyard, in one specific spot, face northeast, don't move and hold breath, can get a call... .maybe. Absolutely terrible. Average home price $1 mil +. Seems closer to power lines, worse the situation gets. Need a tower in this area.

Extremely spotty reception in this area with all carriers, not just AT&T. Sometimes I'll get full reception, sometimes no service in the exact same location in my home. Driving through the intersection of 76th and Thompson Peak will cause a dropped call no matter what.
