title: Ads Network Reporting for iPhone
body: <p>I'm Curious about how all the ad mechanism works.
  Let's say I publish my app using 5 networks (adMob,inMobi, etc...).
  Each network gives me a slice of code to incorporate inside my initialization function, so
  when the app is downloaded, the report will be sent.</p>
  
  <p>Now, someone downloaded my app using one of these networks, let's say by pressing an adMob banner.
  Is there a way for my app to know at startup that it was downloaded using adMob, so I won't call all the other 4 network initialization code? I don't see a point making all these redundant calls.</p>
  
  <p>Thanks</p>
