For the most part I am very happy with my 3G Iphone and I don't seem to have any dropped calls, even driving around on 3G. I did notice one thing that was kind of weird though. Before I bought my 3G Iphone and switched to AT&T I had Verizon for years with multiple different phones. I have terrible cell phone service in my house. I could barely make a call on Verizon and always would get dropped calls in my house. I only have 1 bar on Edge in my house and I can make and recieve calls with my iphone no problem, I rarely get a dropped call. Here is the strange part, when I switch to 3G inside my house, I get "no service" on my iphone. It just sits there and doesn't drop back to edge. If I manually switch off 3G I am ok, but as soon as I switch to 3G on I get "no service" again. Anyone else have this problem where the phone is on 3G but won't drop to edge?
