title: iOS: adMob for universal App?
body: <p>I am implementing adMob ads into my Universal App. In the www.admob.com, it has two options for ads: one for iPad app and one for iPhone app. My question is that do I have to make to two different ads with two different publisher IDs for my universal app or just make one ads with one publisher ID for my app and then change the ads size inside the code? Thank you</p>
