The Missing Sync for hiptop synchronizes your contacts, calendar events and to-dos between your hiptop or Sidekick device and Mac OS X's Address Book and iCal applications. The Missing Sync uses Mac OS X technology to synchronize your data with the hiptop or Sidekick Web-based Desktop Interface. Any changes are then transmitted right over-the-air to your hiptop or Sidekick. Very cool.
