Apple is supposedly having an event on September 10, and one of the rumored announcements for this hypothetical event is the final version of iOS 7. While support is planned for the iPhones 4, 4S, and 5; the fifth-generation iPod touch; and the iPad 2, iPad mini, and both Retina iPads, a report from 9to5Mac says that the tablet builds are running behind the phone builds and may be delayed slightly. Citing “chatter within Apple” and a feeling among developers that the iPad builds are relatively “unstable and unreliable,” the report says that Apple may opt to upgrade its tablets in a 7.0.1 release that trails the iPhone’s upgrade by a few weeks. The beta builds of iOS 7 also came to the iPhones first—the public beta introduced after WWDC supported iPhones and iPods, but it wasn’t until Beta 2 was issued two weeks later that the software could be installed on iPads.
