Since 2006, Greystripe has distributed free games and apps to over 1,400 different mobile handset models and currently offers a catalog of 800 games. Greystripe allows developers to add pre-roll (before), interstitial, and post-roll (after) ads for use in their games.
For now their strategy is simply to get on as many iPhones as possible with free or inexpensive games [Jirbo Games on App Store].
Jirbo's formula is simple: create applications that build on familiar games and themes, add a dash of whimsy and top with rich graphics.Jirbo, however, has gained some notoriety amongst iPhone developers after they renamed their applications with leading spaces so they would appear at the top of any alphabetical listing. They have since abandoned that plan.
With Apple's easy App Store upgrade process, Jirbo or other companies could easily integrate ads into existing games by including it future versions.
