Tips: Freeing and conserving storage space
Try to maintain at least 400 KB of available application storage on your BlackBerry® device. If you find that your device
processes are unusually slow, try freeing storage space by deleting files that you don't need. Changing options for email
messages, calendar entries, and media files might help you conserve storage space.
