I bought an ipt 3g about a month ago and without knowing iTunes updated my phone to 3.1.3 rendering it un-jailbreakable. I've since returned and bought a new one. I don't want iTunes to update again. I haven't even loaded iTunes yet or opened my ipod until I can confirm that I need to some how disable automatic firmware updates. Also can I backup the 3.1.2 fw in the even it does get updated? I appreciate any of your feedback. Thanks everyone. Great forum.
