well i am most likely going to jailbreak, but as stated i have a question about backing up when my iphone 4 is jailbroken through iTunes. so if im jailbroken and i want to back up my app store apps and the non jailbroken stuff through itunes. now say i want to restore my iphone 4 to get rid of the jailbreak, and say i restore from backup (the backup i did through itunes while jailbroken) will i still have the app data from my app store apps and no longer jailbroken? thanks in advanced because this question has been pestering me.
