Thanks for the information. To me with a white screen the phone is useless. If I had of continued to use 4.0 Firmware and jailbroke the phone with jailbreak.me as I actually did - This was not going to fix my white screen. I did proceed to follow all of the recovery methods to get rid of this, but had no luck. In my opinion I had no choice, but to restore in Itunes to get rid of my white screen. Hindsight, I should have posted with white screen problem prior to restoring in Itunes.
What is the deal with restoring in Itunes with an active AT&T customer's sim card. Will they get in trouble somehow through the activation locating them on a different phone. How does an Inactive AT&T sim card work when it is not registered for service. Are both the method's above going to work. I did get the phone for free and have no intention to use it as a phone, just for Internet/email/contacts/calendar. Thanks for staying with me on this post.
