RIM kicked off BlackBerry DevCon today with plans for its own mobile ad service in the vein of Apple's iAd or Google's AdMob. BlackBerry Advertising Service will give app writers access to multiple ad networks to subsidize free or cheap apps. Developers will get a similar 60 percent cut of any ad revenue, but RIM is hoping to avoid iAd-level control and will give the advertisers and ad networks direction over the creative presentation of apps.
