Is it just me or does anyone else have trouble removing thier battery cover? Sometimes it comes off really easily and sometimes it won't come off at all. I lost patience with it last week and tried to get it open with my car key and scratched it. I think the cover should have some kind of grip on it so that your finger/thumb doesn't slip when you try to open it. Now have a new cover on order from HTC, hopefully the new one might be easier to get off.
