Pinger -- a mobile voice messaging service -- today released an application enabling Mac users to quickly upload Address Book contacts as message recipients. Pinger supports Address Book as well as Microsoft Entourage, and Mac users can import contacts to instantly send voice messages. Pinger works with all major carriers and mobile phones in the U.S., and offers a system preferences panel that allows users to select which folders to synchronize with the Pinger service. The panel works on Mac OS X 10.3 or later systems, and the software is available for free as a public beta test.
