So I'm really excited for the upcoming 2g jailbreak, and I have some questions. 1. How much space do apps from Cydia / Installer take up? Is it the same amount as the normal apps in the official App Store? 2. I'm on 2.2 firmware, what exactly do I need in order to jailbreak? I've heard you a need a 2.1.1 "bootloader" or something? 3. Will the Jailbreak process delete all my stuff on my iPod? 4. How does Apple backup iPod Touches? I've heard people say, "Just sync it and it'll backup" ... What? THANKS!
