Guys, I am having major issues with my iPhone 5 on iOS 7.0.4. I am facing constant call drops, lose my 3G connection and do not get any network. It is happening too frequently and is driving me nuts. I have another iPhone 4S with the same network provider and that has no issues at all. I use both phones in exactly the same locations. I am facing this problem for the last 8-10 days and I am very worried! Please help!!! Oh and also, my phone is not in warranty anymore. :-(
