Optional: Booting Tethered - When you Jailbreak your iPod Touch running the official iOS 5 you will have a tethered Jailbreak. Meaning in order for your iPod Touch to turn back on you will need to boot it using RedSn0w (this applies every time your iPod Touch looses power). To do this launch RedSn0w again and click the Extras button > then click the Just boot button and you will need to put your iPod Touch into DFU mode again.
