Well, that was speedy. Not too long after iPhone 2.1 arrived to fix most of iPhone 2.0's most damning problems, Apple has seeded OS 2.2 Beta 1 to developers. No one's had a chance to dive in yet to see what's new, but some mo' bug fixes, push notifications (finally) and added GPS features sound like a good bet, now that most of the bigger bugs are squished.
