A microSD media card is a removable flash memory data storage device. When inserted into a BlackBerry smartphone, it can extend the memory available for storing media files such as videos, ring tones, pictures, or songs.

Luckily the prices have dropped considerably over the past year or two and you can pick one relatively cheap.
