I am planning on making my switch from Sprint to ATT at the end of the month. I will be getting an iPhone & my wife just wants a phone that "makes phone calls & can take a picture" every so often. I have heard complaints about dropped calls in the Phoenix area (I am around 60th St. & Greenway). And I have also read that the iPhone drops calls more frequently than other cell phone varieties. Can anyone in the Phoenix area give me their experience with ATT here in the Valley? Thanks.
