so i just switched to a blackberry pearl 8100 and i put in my sd card from my old phone but it doesn't show up on my pearl anyone know how to fix this?
Here's how to enable your media card:
Status / Options / Media Card
Media Card Support: On
Encryption Mode: your choice
Mass Storage Mode Support: On
Auto Enable Mass Storage Mode When Connected: Prompt
Plug the BlackBerry into a USB port, answer Yes to the prompt, and the BlackBerry Media card will show up as a disk drive in My Computer. Then you can drag and drop between the PC and the Media Card.
For most purposes, Mass Storage Mode is much better than Media Manager. The only time you really have to use Media Manager is to get pictures out of your device memory. Mass Storage Mode can't see the device memory. Once the pictures are on the Media Card, Mass Storage Mode will let you drag and drop between the BlackBerry and your PC.
