hey guys i have a few questions about blackra1n jailbreak: 1.I know its teatherd so when i shut it off will i have dto re-jailbreak on computer? or do i just run the "blackra1n" app on my spring board? 2.When we say "re-jailbreak" does that mean my ipod forgets all about it and erases all my third party apps? eg.cydia? winter board?etc.. and its running 3.1.2 firmware so third gen.
