Firmware 2.1 for iPhone is set to arrive sometime in September. We’ve heard about various beta updates and it appears there’s one more. Beta 4 will disable the service which allows background data for native applications.

That means that the push notification data has been suspended for an indefinite period of time. It’s likely to return when Apple feels ready. Hopefully they will get they feeling by September since the push thing is for some the key feature in their iPhone.

Apple says that the notification code will be off limits for further development, without offering more information about future betas. I guess third party developers will pause any application that could use the push service until Apple finishes of the further development thing.
