My girlfriend has an iPhone 3G that is unlocked to 3.1.2 via blackrain. Since the phone has been updated to 3.1.2, it lost the ability to sync because when we try to sync it, it says that it has already been synced with a different computer which is bogus. Is there an app in cydia or anything that can change the id of the computer to allow her to sync again? Another thing is push notifications don't work anymore. They used to work but not anymore. I installed some push fixes for her but they don't seem to work. Any help there either? I created a custom firmware for her running 4.0. When she tried to install the firmware, it gives her an unknown error 1006. Any clues to what that means? Is it worth it for her to upgrade to 4.0? or do you guys think she should stay on 3.1.2? Thanks in advanced.
