Hello, I am having a problem with my iPhone 4 signal. I am on the 3G verizon network and where I live I gets full 5 bars. Last night, I went to a party and the house was way out where I could not get any signal at all. Since last night, my signals bars is no more than 3 bars. I am at home right now and I usually get full bars and it is only on 3 bars. I've shut down the phone 3 times today and it did not solve the problem. Does anyone have any ideas?
