Hi guys. I'm having an unjailbroken iPhone 4S, which is running the pre-installed iOS version --> 5.0.1. Recently I'm having some problems with my network. Sometimes when I try to use my network (3G or wi-fi), nothing seems to be working. Safari/Twitter/Email/Streaming etc. It says I'm connected, but it doesnt work at all. After I reset my iPhone (DFU mode), it works fine again. But this problem seems to be occuring very often, suddenly. At least once a day. Any help, please.
