I plan on upgrading to 3.1.2 (I'm on 3.0 right now and have a 2G iPod touch 8GB). Immediately after I upgrade, I also plan on jailbreaking with blackra1n. 1. Can I upgrade to 3.1.2 by just restoring my iPod? 2. If so, after I'm done upgrading, do I choose "Set up as a new iPod" or "Restore from the jailbreak of ..."? 3. If I choose "setup as new iPod" do I still get to resync my music/apps after I'm done with jailbreaking?
