Well, I guess that November 21 rumor was true, because the iPhone 2.2 firmware update is now available. This one is pretty hefty in the feature department too, so color us excited. You’ve got the a few nice enhancements to Maps, including Google Street View, public transit directions, walking directions, and the ability to share your GPS location with others via email. Speaking of email, the Mail client enjoys some stability improvements in this release as well, along with better handling of wide HTML email. Safari picks up performance improvements, we get the promise of fewer set-up failures and call drops, and better sound quality for Visual Voicemail.

If you’re a podcast lover (and seriously, we know that you love our shows,) you’ll be ecstatic to hear that, finally, podcasts are available for download in the iTunes application. Seriously, this thing is packed. Connect your iPhone up to your computer and grab the 246MB update now.
