I am a relative novice with these issues and need some help. I have a iPhone (3.0). I was asked to upgrade when syncing today with iTunes. I seemed to successfully upgrade but now beside the phone function and text nothing else works. It seems to not be able to connect. I do not know (or think) that a coincidence is that I now cannot get my desktop to connect to the internet even though I have a strong signal. Frustrated. I have loved this thing until right now. Help!?!
