Prototype Interactive, the Middle East company behind the Yalla Apps service, which enables local developers to publish their apps into Microsoft’s Windows Phone 7 Marketplace, announced updates to its service intended to be “even more convenient to the community.” The company has made three significant changes: support for paid apps has been added, enabling developers to generate revenue from WP7 app sales; an alternative payment method has been added to enable developers from Pakistan and Egypt to take advantage of the service; and a “more convenient charge structure” has been added, to enable developers to submit “many more apps – free or paid – with their annual subscription.”

Yalla Apps forms part of Microsoft’s Global Publisher Program, which enables developers to submit products to the Windows Phone 7 Marketplace via an intermediary in markets where Microsoft does not have a direct app presence. Prototype Interactive said that since its launch during Microsoft’s Tech-Ed in March 2011, the service has been “embraced by the developer community.” Alexander Rauser, CEO, noted: “We are excited about this major update to Yalla Apps as it is a direct response to the feedback we got from the developer community.”
