DevTeam says that 2.2 update SHOULD NOT be applied using iTunes if you want the chance of a soft-unlock in the near future. Use new version of PwnageTool (not avaliable yet, but will be soon).
Some fact:
The 2.2 firmware for 3G contains a baseband update for the 3G iPhone
The 2.2 firmware for 2G (1st gen iPhones) doesn’t contain a baseband update and the baseband is still at 04.05.04
Pwnage technique (and therefore the Jailbreak) isn’t affected, but PwnageTool and QuickPwn do not support this release as yet, so DO NOT install 2.2 using iTunes as you will lose your jailbreak
If you apply this update and you previously relied on PwnageTool or QuickPwn to activate your phone, it may become temporarily deactivated and unusable (until we release the new version of PwnageTool or QuickPwn).
PwnageTool and QuickPwn updates will be released as soon as possible that will allow a safe update path to 2.2 the release of these updates is inevitable but not imminent, we are creating the modifications right now and we need to put the new software through the usual testing process.
If you apply this update and you have third-party (non AppStore) applications from Cydia and Installer that you rely on they will stop working.
2G (1st gen) iPhone users who cannot wait for the new PwnageTool or QuickPwn can safely “Update” to 2.2 using iTunes, this will preserve the existing activation. However “restoring” to 2.2 using iTunes will return the iPhone to the unactivated state. If you are in any doubt just wait. NB: This works for 2G ONLY.
The use of SIM-Proxies (small circuit boards/chips that sit underneath the SIM card) to provide GSM/UMTS service on your locked iPhone 3G: early reports suggest that the 2.2 update disables the functionality of these devices.

Be very very carefull. Because there are so many fake web sites came out recently. Do not trust names like quickpwn.com. There sites pretend to be DevTeam. Applications that those sites give you might be dangerous for your iPhone. Some sites ask for donations. Remember DevTeam don’t do it.
There is only one DevTeam’s site: http://blog.iphone-dev.org. When I publish news about some new version of QuickPwn, WinPwn, PwnageTool and etc, I use links from DevTeam’s site. Everything else could be harmful fake.
QuickPwn for Windows is updated. Support for all 2.x firmwares is added. So now you can QuickPwn and jailbreak the device if it is running 2.0, 2.0.1 or 2.0.2.
DevTeam reminds that it is still beta software, so usual rules apply, no complaints if anything goes wrong and use the tool at at your own risk!
Using QuickPwn does not update the firmware itself, this tool is designed to ‘Pwn’ (the ability to install future custom non-Apple firmwares) , ‘Jailbreak’ and install Installer and/or Cydia on a given device. If your device is running 2.0.1 and you QuickPwn it, it’ll still be running 2.0.1, although it will now be Pwned and Jailbroken. It will also activate (not unlock) devices that are being used outside of their intended territories and cannot be activated using iTunes.
If you want to update to 2.0.2 then use the normal iTunes update to get to 2.0.2 and then use QuickPwn to Pwn, Jailbreak and Activate, remember that the 2.0.2 update includes a baseband update for the 3G iPhone, so depending what your long term intentions are for the phone, update wisely, of course in the upcoming PwnageTool application you’ll be able to create a custom ipsw without the baseband update enabled.
