Research In Motion is working on a way to download apps from BlackBerry App World through carrier billing services rather than PayPal. This would be an especially useful feature for those who prefer not to have a PayPal account.

RIM CEO Jim Balsillies announced the upcoming bill carrier changes at the BlackBerry Developer Conference. This will also make it easier for spontaneous purchases.

Soon a BlackBerry Theme Studio will be launched. This will make the user interface more customizable and there will also be a new advertising service for developers to integrate ads into apps.
