I've been trying to set ringtones for certain contacts in the contact list. The application lets me get to the screen to select the ringtone I desire and then I hit OK, but the contacts record still shows 'default'. Similarly, if I attempt to assign a contact to the favorites list, the 'star' turns yellow when I click on it, but once I leave the contact & return, it has not been set. Similar results if I click & hold on any contact and then select 'Add to favorites' from the popup menu. Is there a contact list corruption issue or possibly a bug here?
