More iPhone-Related Announcements Tomorrow?

We've heard some unconfirmed rumblings that Apple may be set to reveal two more announcements related to the iPhone on its launch day (tomorrow). The source is uncertain what these announcements could entail, or whether they concern already-leaked information (i.e. .Mac iPhone RSS Reader).

Of course, Apple has yet to announce iTunes 7.3, which is a requirement for the iPhone. One rumored feature of iTunes 7.3 is the ability to make iTunes custom ringtones, although this has since been disputed by ThinkSecret.
