My iPod Touch 2G 3.1.1 has been jailbroken but i would like to upgrade to the jailbreak 3.1.2. When i attempt to upgrade the firmware with iTunes i get the message: The iPod could not be restored. This device isn't eligible for the requested build I did some googling and there was mention of ECID and SHSH and such. Confusing stuff. I just want to know is it POSSIBLE OR NOT to upgrade my existing firmware to 3.1.2 (or better), and if so how?
