Its just the weirdest thing. Today, December 2nd, 2011, my brand new iPhone 4S started acting weird. I don't know what is going on. I have tried to reinstall 5.0.1 and nothing happens. Basically, I am able to make and send calls but my iPhone says there is "NO SERVICE". It so odd. No service but I can receive calls and make them. I taking it back to Apple to have them look at it. My parents 3GS are not affected by it for some odd reason even though they are running 5.0.1. I am wondering if anyone's iPhone is doing this too. I also want to note that there is no internet and I can't send text messages. This is some time after while I was still on the phone, Wi-Fi was on. After that, I turned off my Wi-Fi and called my Mom's iPhone and it went through. I want to here some thought on this.
