Need assistance and/or samples of MS Sync Framework

Hi,

We are in the process of developing an application which needs database sync between a Mobile app and a DB server. This occasionally connected application (OCA) needs to synchronize with the the server DB. We are using SQL server 2005 and the .NET 3.5 Framework.

Can anybody suggest or help us with implementation of the MS Sync Framework? 
In particular any methods or samples (or pointers to samples) will be very helpful.

Regards,
Sudhir
