If the Apple App Store just doesn't do it for you, you'll now be able to get your iPhone apps from the new iPhone Download Exchange from mobile advertising platform AdMob.
CEO Omar Hamoui says iPhone developers are finding it harder and harder to get their apps discovered in a world increasingly saturated with ever more useful/retarded things to do on your iPhone (ew, did someone iFart?). The new exchange helps developers get awareness for their apps by using AdMob's mobile advertising platform to cross-promote all apps via ads on other apps in the download. (Most apps already have paid-for apps running in their software.)
The exchange is currently home to 1,000 apps.
