I have an iTouch running a jailbroken 1.1.1, and it's perfectly fine, but there are a few toys in the appstore I really want. Most of the guides I've seen for jailbreaking don't really handle the transition from 1.1.x to 2.0.x to well. I have a copy of the 2.0 and 1.1.2 firmware on hand, but I never saw teh need to upgrade. How should I go about updating form 1.1.1 to 2.0.x? I have nearly 4gb of apps and I don't feel like re-doing all of them, is there a way to transfer them over?
