Sarasota, FL - Retrieval Dynamics Corp. (RDC), a provider of mobile application services that boost business productivity, today announced that it has signed a BlackBerry™ ISV Alliance Agreement with Research In Motion (RIM) (NASDAQ: RIMM; TSE: RIM). The agreement will enable Retrieval Dynamics to optimize its current wireless applications for the popular BlackBerry Wireless Handheld™ and provide new solutions designed for RIM's enterprise customers.

Under the program, Retrieval Dynamics will work with RIM to customize the interface for DocLYNX Lite, RDC's real estate industry application.
