I was in a car and my brother had service and I didn't. He was talking on an iPhone 4.
And my iphone will go back and forth between 4g and edge. There are other people experiencing issues with reception. I think it has todo with lte. I turned lte off in settings and reception is better but i shouldn't have todo that.
If apple puts out an update to fix this issue I want to be able to update without losing my jb if one is released for the iPhone 5.
