I have a new 4s.* Got it on Oct 14th and have had zero problems.* Well all of the sudden it constantly says "searching" and will then say AT&T then freeze for a second then go back to "searching."* I have an AT&T MicroCell which has given me no problems.* I disconnected that and the same thing happens, so I know its not my MicroCell.* I reset the network settings to no avail.* Will restoring through iTunes help and afterwards will it put my phone back to the way it was? Anyone experience this?* I doubt my phone is defective.* Could this be an iOS 5 bug?
