Hello, I currently have a jailbroken iPod touch 2g running on 2.2.1 firmware, but is still tethered. What is the best jailbreaking program that I could use to go untethered? Redsn0w 0.3? Can I simply take a tethered iPod, run the program, and have it become untethered? Seems to simple. Also, I'm on a Mac. Thanks.
