I have been thinking about jailbreaking and unlocking my ip4 but was never confident enough to do it. I am confused about the steps and what software to get and what files to save first. ex. shsh blob and firmware version mumbo jumbo. What are the steps to jailbreak and unlock a ip4 4.1? thanks i have jailbreak iphone 2g before but now it seems to be more complicated. another question is..... i still have the ip2g but updated to 3.1.x. i m stuck in itunes activation screen. how do i activate it without itunes and then jailbreak it?
