Hey guys I recently bought an ipod touch, and was planning on jailbreaking it. However, mine is of the 3G 3.1.2 with MC in the serial number verity. I have read multiple times that blackra1n cannot jailbreak these ipods, and that I must look for another utility. So far, I have found my options are either to rollback the firmware, which I cannot find a tutorial for, or to find another jailbreak utility. Do you guys have any suggestions in the matter? It would be greatly appreciated. NyghtByte
