It's not the GAL, there are only 40 people in there. There was a Public Contacts folder with over 2000 contacts. This is still appearing on the handsets. I have now deleted the contacts from the public folder, deleted the user account from bes and wiped the handset. Whenever I do an enterprise activate all 2000+ contacts sync whilst activating. I have no idea where these are coming from now, since I deleted the public folder contacts..
