I should try this!
I have an android phone so its already jailbroken! =D
I don't have enough money for one :( But when I get one I'll do it!
My brother recently got a iphone 4, I'll show this to him.
I was actually just looking for a reliable guide for this! Appreciate it. :D
new jailbreak is out! :) for 4.2 http://greenpois0n.com/
