Developers will be able to simultaneously integrate Greystripe and other mobile advertising networks - immensely useful for those interested in optimizing for maximized revenue and fill.
There are quite a few options out of the gate for AdWhirl developers. Greystripe's iPhone banner product suite includes expandable to full-screen rich media Immersion ad units (which are ideal for those that don't want users leaving the application - useful for advergames, video and mobile websites). These expandable banners utilize Greystripe's Lightning Technology, which delivers Flash ads to the iPhone as HTML5.
"Greystripe's expandable immersion ads are the most engaging available today, which means great revenue for application developers," said Greystripe VP of Publisher Relations Erica Chriss. "We're excited to be working with AdWhirl to widen our base of developers."
