First off, sorry if they have been answered a billion times 1. Does it void my warranty 2. If ANYTHING goes wrong, can I just restore. When I had a nano and used ipod wizard/linux, I could restore basically at any time. How about for this? 3. Do I need to do any extra steps with the automatic jailbreak for windows (which is stickied at the top) to get it to sync with iTunes? 4. How would I go about to get a custom wallpaper or icons once it's jailbroken.
