I tried to upgrade my girlfriends iPhone 3Gs to the GM 4.0 and an error occurred. So I restored the phone and the connect to iTunes screen came up. So I plugged it back into my computer and now I'm getting an error that says "We could not complete your iTunes store request. An unknown error occurred (-9812)" I reset my modem and router and did other basic trouble shooting. Same thing keeps popping up. Please help!!! She's gonna kill me if she finds out i ****ed her phone. My internet is working.
