Hello, I am running 2.2 on an jailbroken/unlocked iPhone 3g. I recently have been getting a white screen every now and then and feel that a restore would be good for the phone. I am wondering if someone can tell me the best way to restore my phone. Is it possible to do so without locking it again? Also, is it possible to upgrade to 2.2.1 yet? If so, can someone tell me or point me in the right direction on upgrading my phone to that? I lived in Seattle before and payed someone to unlock it with 2.2, I don't live there anymore and my sources are very limited, if I could learn to do it myself, that would be great! Thanks, I hope to hear back soon! I'd love to do a restore tonight or sometime soon!
