How are these two issues related? The ad would be on your home screen only and not be visible when you start an application. - Also, as seen from the concept screenshot, it would only be part of a panable screen area, so it wouldn't even always be visible. Plus, you could choose a non-subsidized phone without an ad if it really annoys you. A smaller screen doesn't suddenly get larger when you start an application. You also cant make it bigger by paying the full price. So what's the point you're trying to make?
