Hi, I have a jailbroken iPod touch 4g and am thinking whether to update or not. I have a 25.0 GB data cap and the frequent updates are really eating into it. I hope that someone can list all the small or big changes, such as bug fixes or changes in battery life, (other than the location services) that makes it worth downloading. Currently, I edited the hosts file so that my iPod will not update. And I just jailbroke it so I don't really know how much work an update will cause to rejailbreak so I am quite reluctant. Thanks.
