I have a problem with one iPhone 3GS. Everytime the user creates a calendar entry in groupwise main calendar, its synced to the iphone to a subcalendar of groupwise.
In GroupWise its definitely in the main cal.

I've changed the default cal. on iphone - but nothing happens. It's always synced to the SAME subcalendar.

iPhone 4 Users does not have this problem... iOS on 3GS and 4 are the same... (4.2.1).

Any Ideas ?
