  • 6. Point to NOTE• BUILD FOR EVERYONE - An application built in BlackBerry JDE 6.0 runs on a BlackBerry smartphones running BlackBerry Device Software 6.0 and later. It DOES NOT RUN on a BlackBerry smartphones running BlackBerry Device Software 5.0 and prior.

Ads in your App (little revenue) – you need to install the AS SDK which is <1mb download and create an account3. Charge for the App (higher levels) – you need to install the PS SDK which shouldn’t be too hard4. No operator billing yet – hard to buy Apps directly from mobile money
