...apologies for jumping into this thread as well, but we're also seeing this behaviour on our newly upgraded BES 4.1.3
When I wipe and EA a handheld, the timezone defaults to Casablanca GMT and I have to manually change it on the handheld.
Is there a way to force this from the BES? I would have thought that after a predetermined time it would check in with the BES and sync it's time/timezone info but that doesn't appear to occur.
