Well I've had my BB flip since early December, and sometime mid-December only a couple of weeks old and I somehow broke my outer screen.
Now I've been waiting... waiting... waiting... to see replacement screens come on the market and I still have not seen any anywhere, what the hell? Its April now and the phone has been out for months.
All I can find are the cases and covers, no actual screens.
Last month I saw a thread in this forum where someone found a replacement screen, might have been the main screen. You could do a search to find the post and ask them.
