Long story short.. Got a new 3g iphone. Activated it, working fine. Used back-up of old iphone, new one starts acting weird. Download 2.0 to do a restore. Do restore, phone tries to activate again. Get repetition of error (-9838) Keep trying till suddenly my phone has opened up again. I can use it for calls and whatever, so I assume that's that. Notice all my data has gone, so attempt to sync. Except now when i plug it in it hangs again on accessing itunes store, and then cuts out with an 'unknown error (-4)' So now I can't sync it. Is this a server overload or has itunes somehow broken the phone?
