Should you update...not just yet if your on a Jailbroken Device or if you want to jailbreak, because it is going to take some time to port the 2.0 applications to 3.0. I dont know about you but i have tons of apps on my 2.2 ipod touch and im notgoing to get rid of any of them. If not planning on jailbreaking then go right ahead. I assume that you wont have anything to backup because it should all be in iTunes.
