Clarify if they do not understand, if jailbreaking apple tv 3 have 5.11.07 baseband or iPhone with a different one, you can not release it with Ultrasn0w, may only be released if you are using baseband 04.26.08 and if you are on 3.0 or 3.0.1 and want to go up to 3.1. 2 and not lose that baseband, you must use the Custom Firmware 3.1.
