Ipod firmware is: 2.2.1 (5H11a) Model is: MB531LL 16gb. Currently, there is nothing on the ipod, so have nothing to lose. It is not already jailbroken. My other ipod is at 3.1.3 (updated as it came out). With this one, trying to shift click the update button and loading the ipsw file for 3.1.3 or even 3.1.2 doesnt work anymore. i believe it has to do with apple because they stopped signing the updates? (something along those lines). Only update i can do is the latest. And im not sure if there is an "untethered" jailbreak for the latest update available (for my ipod type). if there is, that may be the better way instead of trying to go to 3.1.3? what do you guys think is the better firmware to go to for jailbroken (untethered). if not the latest one from apple (the one that can be installed easily), how do i go about upgrading to the 3.1.3 version or the one of your suggestion? thanks, awaiting reply.
