I've looked at all the forums telling about the media card and taking out the battery. I've done all of that. I have an AT&T blackberry 8110 pearl and the media card is a 2gb micro sd sandisk. Media card support is on, Mass storage mode support is on and it says Auto Enable Mass Storage Mode when connected: yes
It says media card cannot be read. Verify that the memory card is formatted. I pressed install media card and when I format card, it says Media Card Format Failed. I don't know what else to do. I got a card reader and that didn't even read it. I know the card isn't messed up b/c it worked with my old blackberry 8100 pearl, but I got an upgrade b/c the media card slot broke.
