Google announces new mobile advertising. If you’ve chosen to show ads on iPhones and other mobile devices with full internet browsers, you can now target specific mobile devices or carriers.
This feature makes it easier for you to reach the right users if you have a carrier- or device-specific message. This includes landing pages that have been optimized for a specific device, billing relationships with certain carriers, or mobile apps developed for a specific platform. For example, if you sell iPhone cases, you can use device targeting to ensure that users with Android phones won’t see your ads.
