while trying to insert the media card in my blackberry curve 8310 i accidentally pulled out the gray thing that holds it down, like the same thing as the think that holds down the sim card only it holds down the media card. i tried just putting the media card in with the battery holding it down but it doesn't work, i bought my blackberry curve from wal-mart. I also tried putting it back in but it just won't go back in, is there any place i can take my phone in to get fixed or exchanged?? i still have the receipt, what do i do please help?!?!?!?!
