Soon after the release of revamped Android Market by Google, RIM announced the new and improved version of Blackberry App World version 2.1. The new version of the storefront will gratify both developers and owners of BlackBerry smartphones and allows developers to use RIM’s Payment Services SDK to enable in-app payments in future and existing applications.
[advt]Vendors will be able to register and manage virtual goods through the BlackBerry App World Vendor Portal and a reporting feature will be able to track purchases/payments for their goods. In-app payments will be subject to the same revenue share splits as offered by the BlackBerry App World storefront and use the payment type users specify in their BlackBerry ID (either a credit card, carrier billing or an online payment service such as PayPal).
Letting users download an app for free and pay later through an in-app purchase of additional content has proved successful in other app stores. It is credited as being a significant revenue generator for developers using the App Store.
