Trying to get a Windows Mobile HTC Touch Pro 2 to sync with Mobility 115 using the self signed cert created during install.

We have followed this MS TID: How to install root certificates on a Windows Mobile-based device to import the cert onto the device and a root cet issued by "DataSync Web Admin" is shown on the device expiring in Oct 2010.

However, we still can't get the initial sync to work. It works fine on iPhones and Palm Pre, you can just accept the cert in their web browsers.

Anyone else got a Touch Pro 2 to work? Would a real cert fix this?
