Mark/Space on Tuesday announced the release of The Missing Sync for iPhone 2.0.1, the new version of its data synchronization utility for Apple’s iPhone and iPod touch handsets. The application allows users to synchronize data that the iPhone won’t ordinarily synchronize with the Mac, such as notes, documents, and tasks and archives text messages on the iPhone to the Mac as well as archives call histories, and features a “Migration Assistant” of its own that lets you transfer contacts and other data from another smartphone to the iPhone.

The new version, a 12 megabyte download (courtesy of MacUpdate), adds the ability to create ringtones for the iPhone by using a built-in ringtone editor. According to MacNN, users can simply select a song from the iTunes music library and place it in the editor before trimming and naming their customized ringtone, which is then automatically added to iTunes and ready for transferring onto the iPhone the next time a sync is initiated.

Missing Sync for iPhone 2.0.3 retails for US$39.95 and requires Mac OS X 10.4.11 or later and iPhone OS 2.1 or later to install and run.
