LOS GATOS, Calif.- April 5, 2005 - Mark/Space, Inc. today announced The Missing Sync™ for Windows Mobile, a substantial update to The Missing Sync for Pocket PC, synchronization software that connects Pocket PCs and Windows Mobile Smartphones to computers running Mac OS X.

The Missing Sync for Windows Mobile offers several desirable features over its predecessor, including contacts and calendar synchronization with Microsoft Entourage 2004 and support for Windows Mobile Smartphone devices, such as the Audiovox SMT5600/Orange SPV C500, i-MateSP3i and Motorola MPx220.

"We have our customers to thank for this release," stated Brian Hall, company president and CEO. "The Missing Sync for Windows Mobile was designed with the most asked-for features and support for the latest smartphone devices, then made more functional with a striking new interface that will be appreciated by existing and new users alike."

The Missing Sync for Windows Mobile adds Microsoft Entourage synchronization alongside its support for Mac OS X's Address Book and iCal applications. Other new features include SyncMinder™ to tell the user when it's time to sync, at-a-glance status that shows useful information about a connected device, handheld clock synchronization and user-created profiles that allow specific sync features to be turned on or off. Earlier favorites are of course still present: Bluetooth and Wi-Fi connectivity, iPhoto and iTunes integration and the ability to mount the Windows Mobile device like a disk on the Mac OS X Desktop.

In addition to new features, The Missing Sync for Windows Mobile has at its core a new plugin architecture that gives third-party developers the ability to create sync plugins for their own applications. "Now, Mac developers can easily add support for Windows Mobile Pocket PC and Smartphone devices to their Mac applications," said Ken Freeman, Mark/Space's director of product management. "To help increase the use of Windows Mobile devices in the Mac market, we're working with developers to grow the number of Mac-friendly applications that can synchronize information with these devices."

Mark/Space has also improved the method by which data is synchronized to the handheld device. The Missing Sync for Windows Mobile now employs Microsoft's Pocket Outlook Object Model (POOM) to manipulate information on the handheld in the same way that Windows ActiveSync does. Advantages to using this method are increased sync performance and the ability to sync a Windows Mobile device between a Windows PC and a Mac.

PRICING, UPGRADES AND AVAILABILITY The Missing Sync for Windows Mobile is expected to be available for download from the Mark/Space Online Store before the end of June. The electronic download will be priced at $39.95; retail packaged CD's will be available this summer for $49.95.

Free upgrades will be made available to all customers who purchased The Missing Sync for Pocket PC on or after April 1, 2005, while owners of any previous Missing Sync product, regardless of platform, will be able to take advantage of a special 50%-off upgrade price when the software ships.
