Generic Sync. support for non-SAP backend

Hi

Does Generic synchronization allows mobile applications to call function module residing in any non-SAP backend.I am not sure about this.

The documentation for MDK says we have to use Business Connector for this.

Where can i find the Business Connector for this purpose.

Which non-SAP backends are supported by Generic Sync framework.
