Following on the 8 betas for 2.0 (released July 11), and 4 for 2.1 (released September 12), 2.2 will hopefully bring us a Push Notification.

The new version is labeled iPhone OS 2.2 beta 1 and is accompanied by a new beta of the iPhone SDK (build 9M2611). Beyond “compatibility testing”, there are no other differences noted by Apple.

I am starting to think we aren’t going to see the update in September, as promised, but who knows. There are still a couple of days left…
