Wirelessly posted (Mozilla/5.0 (iPhone; CPU iPhone OS 5_0 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9A334 Safari/7534.48.3) My iPhone 4 on Verizon has been acting up lately. I've had it since Feb and never had a problem with it until now. It will randomly lose signal and the bars drop from 5 instantly to none. 3G goes away as well. This lasts for about 10 sec before acquiring the signal again. It happens at random so I don't think anything triggers it. It wouldn't bother me if it didn't happen when I'm not using the phone but it has caused pandora, etc to stop streaming music and safari or FB to not load. Anyone have this problem? Any suggestions?
