Hi there everybody! I need some help on bringing my specified iPod touch to the latest firmware, 4.0.2, from 3.1.3. It's jailbroken using Spirit. Honestly for the time being, I don't really care whether it's jailbroken or not, I'd just like to update it. I've seen several threads regarding this issue before, but can I simply click "Update"? Or do I have to Restore, and then Update? Also, will I lose all my app data (i.e. Tap Tap, Angry Birds, etc.)? I've backed it up with AppBackup just in case. I know for sure that if I lose all my app data, I'll have to jailbreak again to restore it. And also, backing up my iPod touch takes FOREVER, I've only been able to do it once, and it took around 15 hours. What will I lose if I have to Restore without backing up? Thanks for your time, I know it sure is a complicated problem!
