Research In Motion (RIM) and Indosat on Wednesday  announced an operator billing option for Indosat’s BlackBerry customers that purchase apps on BlackBerry App World.

Operator billing will allow Indosat’s BlackBerry customers to conveniently and securely purchase apps from BlackBerry App World and charge the purchases directly to their Indosat bill. Customers will also be able to charge in-app purchases to their Indosat bill, which allows for the purchase of digital goods, such as additional content or more levels to a game, to be made without interrupting the application experience.

BlackBerry ID, which provides customers with a secure device-independent user identification (ID) for use with BlackBerry App World (and other BlackBerry services), enables this new payment option in addition to allowing customers to seamlessly transfer their personal library of free and purchased apps when they switch to a new BlackBerry smartphone.
