Hello everyone, thanks for taking your time out to help me (hopefully, lol). I know this question has been asked I'm sure--I ran searches, Google, on here, etc--I couldn't find anything with "exact" help. Here's my situation--I have a jailbroken iPhone, ATT, 3.1.3 (7e18), firmware 05.12.01. I'd really like to update to iOS 4, and still be able to jailbreak. Can anyone help me with the steps to do that? I really don't want to brick my iPhone, so any help would be wonderful. Thanks again so much in advance, and sorry if this question has been asked (and I didn't find it).
