Just jailbroke my white 3G for the first time. Previous experience with jailbreaks on my 1st gen and Touch didn't include the new Back-up function of iTunes. My question is, what happens when iTunes does a backup of a jailbroken iPhone? I'm sure it doesn't back-up the jb apps, but, do I have to worry about the backup being corrupted? If I choose to restore to a non-jailbroken ipsw, I'd like to be able to use my backup so I don't lose app data. Will my iPhone be all wonky because it was jailbroken? This is the biggest reason I haven't jailbroken yet. I don't want to lose my app data every time an update is released or if I have to restore. tnx.
