Xperia X10 :: Micro SD Card Broke While Inside The Phone?

2 days ago my phone randomly looses signal, (I'm in the middle of London in location at which I would normally get at least 4 bars 'H' signal), I wait for 10 minutes still nothing so I try and turn it off, the phone freezes/gets stuck with the 'phone shutting down' message on display.At this point I decide to just take the battery out and put it back in, after doing so the phone will not turn on what so ever. When I get home that evening I try to charge it, nothing, no lights and still won't turn on.

Taking the battery out again, followed by the sim card and memory card I notice that the memory card has a crack in it, all the way across and just under the gold contacts. I think nothing of it as surely this couldn't have happened while it was in the phone and must have been there the whole time, so put everything back in and try again. Nothing. Open it up again and take out the memory card, leaving it out this time I try again and the phone starts up.So Sony Ericsson,
