Well I should have trusted my gut and not upgraded the bluetooth. Ok prior to upgrading my bluetooth to 141 I was able to sync both contact and todo/calendars but for some reason now iSync does no longer want to sync todo/calendars with bluetooth 141. Anybody able to do this? in addition since upgrading to 141 all syncing in iSync seems to be noticably longer.

Can't synchronize calendars and To Do items to Nokia 6600: device is not available. I am using the MSI adaptor which hadn't failed me to date.
