GOLDEN RULE: If you have a 3G iPhone and want potential soft unlock in the near future do NOT use QuickPwn, and do not use the official ipsw or the iTunes update process without using PwnageTool.
Read item 1 again and again.
At the bottom of this post are the bittorrent files for the latest versions of PwnageTool and QuickPwn.

The ‘late 2008’ MacBook/air/pro line of computers have an issue with DFU mode. While it’s possible to go from Pwned 2.1 -> Pwned 2.2 (using PwnageTool), you can’t yet go from stock to pwned. If in any doubt use a different machine.
