Timed with the release of Apple’s newest offering, the iPhone 3G, Greystripe announced today that their in-game mobile advertising network will now be available for the hundreds of iPhone game and application developers who opened up shop in the App Store yesterday.  Greystripe now offers iPhone game developers an SDK which integrates advertising and reporting APIs and creates the opportunity to make money off every use of their applications and every play of their addictive iPhone games.

Many of Greystripe’s 120 existing publisher partners, including Amplified Games, Xgen Media, DS Effects, United Fun Traders, Relaxas and Norbsoft plan to offer iPhone games using Greystripe’s advertising technology and will be able to immediately monetize their new iPhone applications.  Both existing and new publishing partners will be able to take advantage of Greystripe’s already proven results.

Greystripe’s iPhone SDK supports standardized, full screen square (320x320) advertisements to provide advertisers a new canvas size for their brand messages in pre-, interstitial and post-roll inventory.  Application and game developers can add Greystripe’s iPhone APIs and start monetizing their content immediately by signing up at iphone.greystripe.com/register.
