RIM says it plans to launch the new BlackBerry application storefront in March 2009, and applications developers can start to submit their entries from 2008. RIM says that developers will be able to set their own prices for applications and will also get to keep 80% of the revenue. It's a similar business model to i-mode in Japan.According to RIM, its application storefront and the on-device application centre will ultimately give BlackBerry users a greater choice of more sophisticated applications, as well as an easy method for managing installations, upgrades and purchases. RIM is working with PayPal to enable online payment for the applications. It's expected that each of the operators carrying BlackBerry devices will have their own branded version of the BlackBerry application centre.
