That was fast. It's barely Nov. 21 and the iPhone 2.2 update is here, all 246MB of it, as promised. Included in the update, according to the release notes and as we'd heard, are all the new Google Maps features we've been waiting for like Street View (which is so far butter smooth and delicious over Wi-Fi, slightly less magical over 3G), public transit and walking directions, as well as over-the-air podcast downloads, mail enhancements, Safari tweaks, improved sound quality for visual voicemail, fewer dropped calls (again), and more. But you know, not MMS or copy and paste. Grab it now.
