As I mentioned in my 1st post here, I am the new proud owner of a 1st gen. 16gb touch Ipod. I have looked at a lot of info regarding jailbreaking, and have a few questions: 1. First off, can I backup my Ipod, or can I only reset it with itunes? When I bought it, it was already upgraded to FW2.2. If I reset it with Itunes, will it lose that upgrade? (This is why i ask about backup..since I didn't originally purchase the upgrade, will i lose it in a reset situation) 2. If I jailbreak, will i still be able to install from the AppStore? 3. I don't totally understand how the installer.app works. Every post I have read says "once you get installer" etc. Once jailbroken, how do you get and install installer? THANKS!!!
