I have the Iphone 4s, and my girlfriend has the Iphone 4. Well at my parents house there isn't a Verizon area, so it uses the US Cellular towers, through Verizon's extended network. Her phone stays in the extended network a lot of the time, but mine keeps trying to connect to Verizon towers, which causes me to lose service, meanwhiile she has pretty decent service, compared to me. Does anyone have any tips? Verizon keeps telling me to do soft resets, update my phone ( I already have the latest version of IOS). Do any of you know anything about this? I would greatly appreciate it.
