Hey guys. I own a 32GB 3rd generation iPod Touch. I have jailbroken it using blackra1n and it is working perfectly. I have installed many applications using Cydia. Now if I want to upgrade from 3.1.2 to 3.1.3 and use the Spirit JB instead, I would have to restore, right? How do I take a backup of all my iTunes/Cydia apps?
