Hello I am new to the whole jailbreaking thing. I currently have an 8GB 3G jailbroken running firmware 3.1. I really want to make it have 3.1.2 but still be jailbroken. I am currently downloading the 3.1.2 firmware onto my mac and have pwnage tool 3.1 on it that i used to jailbreak. what all do i need to do now to have my phone jailbroken on 3.1.2 instead of 3.1? Thanks for helping a new guy!
