GooSync is a server based synchronisation service that allows you to synchronise almost any mobile device over-the-air with your Google Calendar, tasks and contacts.
GooSync works on any device that is SyncML compliant which includes the latest Nokia, Sony Ericsson and Motorola phones. It also works on Windows Pocket PC, Windows SmartPhone, Palm OS, Treo, BlackBerry and Apple iPhone by installing a SyncML client.
GooSync uses an open standard called SyncML (Synchronisation Markup Language) designed for platform-independent information synchronisation. This allows you to synchronise your calendar, contacts, tasks between your mobile device and GooSync in both directions. You can synchronise your mobile device to GooSync over-the-air using GPRS or via Wi-fi.
