Apple has seeded iPhone OS 2.2 beta 1 firmware to developers for "compatibility testing." Along with the new firmware they have also released iPhone SDK build 9M2611 beta. Most of the speculation circles around a few key features that were missed in the 2.1 upgrade. Of course, it seems Apple had its hands full with connectivity issues and a long list of usability problems that had to be addressed first.
Developers are still waiting for push notification services, and they may have to keep waiting. Apparently, Steve Jobs himself emailed a MacRumors forum member stating, "We’re running a bit late. We want to get it 100% right the first time." The API was seeded to developers in July with the second beta release of the 2.1 firmware. The services would allow apps to receive data from a third party server while the application is not running.
Rumors persist about whether or not some type of "cut and paste" functionality is in the works from Apple in firmware version 2.2. There may be (and there should be) something in the works to facilitate sending text between applications. High demand for this feature along with the recent iTunes rejection of a third party cut and paste app has kept the topic on the front burner. A perfect storm is brewing over the issue now that Google's Android software includes cut and paste functionality.There were four beta versions of firmware 2.1. Plenty of time for more leaks, rumors, and speculation before version 2.2 is publicly released.
