Yeah ive kinda screwed mine as well.

Bad news as the memory card will not register if the back cover isnt on. I expect due to magnetic switch. (F**KING MAGNETS?!?! HOW DO THEY WORK!!??!)

however why i try and buy it says

Kauppa on suljettuna 08.06.2010 - 08.07.2010
Which apparently means
Trading is closed on 08.06.2010 - 08.07.2010.

Why cant they take orders then ship 'em tomorrow?
