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:

Limitations:
Uploading music and movie to iPhone is now disabled on devices with firmware 2.x.
DevTeam posted a screenshot of jailbreaked and unlocked iPhone 2G with new firmware 2.2b2. This is cool that Apple still doesn’t have anything to prevent this.

Many users of jailbreaked iPhones use application called BossPrefs. The developer of this app is creating a new one. The new application will be called SBSettings.
The toggles drop down when you swipe along the status bar. It is very fast and can be used while in any app without exiting the app. Suppose you are in Safari but realize your 3g is not yet enabled. Just swipe the statusbar and toggle 3g, than resume in Safari where you left off. The advantage is there is no need to exit Safari and load settings or bossprefs.
The look and feel of this new app will be something like this:

Apple a bit more than a week ago. Couple more features were hiden there.
First of all Apple has addressed one common request within the iPhone’s Keyboard settings, allowing users to disable the iPhone’s auto-correction.
The other feature is for Japanese market – Japanese emoji icons. The lack of emoji support has been blamed as part of the reason for slow iPhone adoption in Japan.
The third new feature is Street View. It allows users to view panoramic street level photographs in select cities within the Google Maps application.

Hopefully we will see more new features in this and next beta’s of 2.2 firmware.

No news about software unlock for iPhone 3G or jailbreak for iPod Touch 2G.
