Ok - I've been on this all day and need some help. Had a 3G on 4.0 unlocked. Was too slow so decided to downgrade. Successfully downgraded to 3.1 and jailbroke - but phone won't backup as the backup was taken on 4.0 So now I'm trying to hactivate with the 4.0 ipsw. but it's stuck on the 'downloading jailbrake data' part and is not moving forward. It's been over 5 minutes. What do i do?
