Upgrading A Jailbroken iPhone From 2.1 to 2.2

To upgrade an iPhone that has been jailbroken on version 2.1 to version 2.2:
  • Open up iTunes and plug in your iPhone
  • Sync and backup your iPhone
  • Open up iTunes and click Restore to restore the factory default, this should also ask you to upgrade to 2.2
  • Use QuickPwn to jailbreak your fresh 2.2 install
  • Restore your backup
NOTE: You can also use AptBackup from Cydia to backup your jailbroken apps.
