I received a text on my iphone 4 and when I opened up sms, I wanted to delete that msg, but for some reason... it wouldn't allow me to delete it and it was stuck on the page where you have to reply back. I didn't want to reply back, but just simply delete the msg. It was stuck at the reply section so I went to "Reset" then "Erase all content and settings." I Thought this would just erase my data, but instead it erased everything and went back to stock like when you first received the phone. The screen showed no network and was on the "Plug to itunes" image. After I plugged back to itunes it showed that my iphone was activated. I was wondering is this normal? Even if I deleted my data, shouldn't it still have service?
