We all know that iPhone OS 3.1 is coming soon, within a month probably. (firmware update 1) AT&T said that MMS will arrive in late summer, presumably through an update. (firmware update 2) It is rumored that this year iTunes will include a home screen arrangement feature from within the program. This will obviously require an update. (firmware update 3) It is known the Apple typically holds a September event for iPod and iTunes refreshes. This event will probably be around September 8th or so (which is a little less than a month away and also happens to be in the 'late summer' time frame). Because of all this, I think it quite safe to say that the three firmware updates, will actually come in one update. iPhone OS 3.1, iTunes home screen arrangement, and MMS; all next month.
