I want to upgrade to 5.0.1 and then immediately restore from my last backup, which is jailbroken. Will this be bad or will the non-jailbroken data still exist. I don't care about having the jailbroken things, just my music and apps so i don't have to go back and redo all of it. Also, I am not 100% sure as to what restoring from backup means, so any help is great. I could not find this anywhere else, so if it is there I'm sorry.
