How To Activate And Jailbreak iPhone 4 On 4.2.1 [Unteathered] Without Any Sim Card

i made this tutorial on how to activate and jailbreak your iphone 4 on 4.2.1 without any kind of simcard because greenpois0n doesn't do it for you.
This unlock+ jailbreak is unteathered, meaning you can restart you iphone without it loosing its jailbreak or having to connect it to a pc to re jailbreak+ unlock it. HOPE IT HELPS YOU GUYS
PS: remember do delete the reloader .app because we already have cydia installed due to the redsn0w activation!
