What is mass storage, and how should it be configured when syncing with PC or Mac?
Mass Storage Mode lets you drag and drop files to/from your computer to your BlackBerry Media Card. You have to have a Media Card to use it. You enable it as follows:
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.
