In case you haven’t noticed the trend, when Apple releases a new iPhone / iPod touch firmware, it has a tendency to fall to the jailbreakers at mind-boggling breakneck speed. QuickPwn and PwnageTool have now both been updated to support 2.2, though there’s a critical note in here from the iphone-dev team: if you have any interest in unlocking your iPhone 3G in the near future, only use PwnageTool, not the more painless QuickPwn. You’ve been warned!

It’s here. Google Street View and over the air Podcast downloads from
iTunes. Yup, public transit and walking directions too and the ability
to share your location via email. Bug fixes, Safari enhancements, the
ability to toggle auto-text correction, and plenty more… just like we
heard in the pre-rumor run-up. Now get outta here, your iTunes update awaits.
Update: Added some screenshots of the most notable new
features after the break. The Street View implementation seems solid
though we miss the compass feature found on T-Mobile’s G1. Also, the
real-estate saved by moving the Google search field next to the URL
field in Mobile Safari is a welcome and obvious change. As to
auto-correction, well, that’s personal taste.
