I bought unlocked G1, and I do later reset the phone with 'Home' > 'Settings' > 'SD card & phone storage,' then select 'Factory data reset.' Now, when I switch on the phone, must I enter a username and password Gmail data, after there always is information "This could be a temporary problem or your SIM card may not be provisioned for data services. If it continues, call Customer Care". I bought unlock code, but when switch on the phone where it has not entered, because automatically is screen with Android, ask me about Google account ;/ How can I skip this screen??
