By default, the Blackberry Storm is configured to use MTP (Media Transfer Protocol) to sync files from the PC. This is great if you're using Windows Media Player or the software that ships with the Storm to manage your media, but this can present problems if you're using Linux, which I am. At the very least it makes things more complicated to get working. Instead of MTP, we're going to be using mass-storage (Disk) mode to make the Blackberry appear to Ubuntu as a removable disk. On the Blackberry, go to Options>Memory and configure the phone as pictured.
Under Mass Storage Mode Support, select On.
Under Auto Enable Mass Storage Mode When Connected, select Yes.
Hit the Back button, choose to save the changes you made, then plug the phone into your computer.
This concludes the configuration of the Blackberry, in the next step we'll configure the computer.
