LOS GATOS, Calif. - June 1, 2005 - Mark/Space, Inc. today announced that The Missing Sync for hiptop, the company's Mac OS X synchronization software for hiptop mobile devices, now fully supports synchronizing with SunCom Wireless's hiptop and hiptop2 devices. The Missing Sync for hiptop integrates with Apple's iSync technology to provide two-way synchronization of calendar events, contacts and to-do items between a Mac and a hiptop mobile device. Now, SunCom hiptop owners who use a Mac can have their most current information at their fingertips, whether at their desk or on the go. "SunCom is known for providing the very highest level of service to their customers," said Eric Ullman, director of sales and marketing at Mark/Space, "and that's exactly the kind of company that Mac users gravitate towards. We're certain that SunCom's Mac customers will be happy to learn about sync support for their hiptops."
