I think the 2.0.1 update will come in August, with several bug fixes. The 2.1 update will come in September, with a few new features. That would explain whey we have seen 2.0.1 in the wild and 2.1. Odd that they would jump straight to 2.1, but perhaps they are ramping up the development cycle for the iPhone since it is starting to take off and generate them a lot more cash. Either that or they realized they are only going to upgrade the iPhone software every summer, so 3.0 by next July, and they can safely use a new point version every time since the last firmware only got up to 1.1.4.
