The new tools are out, thanks to DevTeam. Here are couple notes:
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.
Preserving the baseband will give you the maximum chance for any upcoming software unlock. To upgrade your phone to 2.2 and preserve the state of the baseband you need to create a custom .ipsw with PwnageTool. This custom .ipsw will not contain the baseband update but of course will still allow all the cool new stuff from 2.2.
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.
Here are download links:

Do you want to jailbreak firmware 2.2? There are many tutorials, guides and howto's came out recently. But I recommend you to stay away from these advices and wait for an official utility with 2.2 support QuickPwn or Pwnage tool.
