I made the adjustment and it seemed to work fine.

It started syncing for around 15 mins but now I get the error:
"Data storage full. Free up some space first."

I found this thread:
http://talk.maemo.org/showpost.php?p=1183924 which pointed the problem at being related to calendars - but I don't have any set up.

Has anybody got any ideas what may be causing this?

Thanks in advance.
