A Russian iPhone site claims to have information on the 2.2.1 iPhone firmware beta, stating that it includes background push notification. Apple first committed to a push notification service for iPhone applications back in June that would allow notifications to be sent to your iPhone even when the applications in question are not running. Apple stated it would be available for developers in September but it was missing from the recent 2.2 firmware update and no official word has come from Apple on the cause of the delay or when it can be expected at this point.
