I've had my iPhone 3G since July '08. I've never had dropped calls as often as I do now. I live in Orange County, CA and it seems that no matter where I go, even with FULL bars over the 3G network, my calls are constantly dropping. I was talking to someone today and it dropped 4 times, all with full bars. I know it's common to every now and then get dropped calls, but this is getting ridiculous, and everyone I speak with has made a comment about it. This has happening frequently, however, each time I think about going to the Apple store to maybe get it replaced, I don't think it will replicate the problem. Does anyone know any fixes for this? Has anyone else been having the same problems lately?
