Hi I do not have any experience with jailbreaking, so simple instructions would be nice . So my uncle quite awhile ago jailbroke my iPod 4th gen 32gb and I checked it is on firmware: 4.2.1. There are some apps on the appstore that requires me to be on IOS 5, I'm afraid of updating the iPod as I know I would lose the jailbreak and have to wait for a new one to come out. Is there a way of upgrading?
