First of all I apologise for the vagueness of the following post, I don't yet have access to the device, GW account or DS server that are involved...

An iPhone user recently configured his device with the DS account. Mail and appointments are synchronizing perfectly but he's getting no contacts synchronizing from his GW account. He's deleted and recreated the account on the iPhone but the same problem exists. The contacts slider on the iPhone mailbox is set to yes.

I'm hoping in vain that it could be as simple as there being no personal address books checked for sync in the DS account but if that's not the case is there anything else I need to check for this problem?

I've checked the various readmes but can't find anything really specific to this.
