Mark/Space has announced the latest addition to the company’s Missing Sync family of synchronization products for Mac OS X: The Missing Sync for BlackBerry (US$39.95). Expected to ship in the first quarter, The Missing Sync for BlackBerry will provide a reliable synchronization environment for owners of BlackBerry devices from Research In Motion, including the popular BlackBerry Pearl smartphone. The Missing Sync for BlackBerry will synchronize information between Mac OS X’s Address Book and iCal applications and the corresponding applications on BlackBerry handsets. Built-in support for Apple’s Sync Services technology means that information can also be synchronized with other Sync Services-savvy applications, including Microsoft Entourage 2004 and Chronos’ SOHO Organizer. Memos will sync with the included Mark/Space Notebook application, or alternatively with Microsoft Entourage or Bare Bones Software’s Yojimbo.
