Just sent my 9810 for repair. I got my brothers 9700 and securty wiped it. When i try linking my email to it via the wizard it says 'The username is invalid. A username must be at least 4 characters'. And in the user name part i've typed my email just as the app world also told me to do. What am i doing wrong? The reason i need to do this is all my bbm contacts are on my email.
