I took on your suggestion and tried both opera/safari and still no ads. Tried to search around on this issue but nothing comes up.
It's very ironic that while every tom, d & h talk about how mobile CTR's are high blah blah, there isn't enough resources to help webmasters on such issues.
I also put in a 100x20 banner for a mobile app in my niche and indeed sales are good. If only I could get the darned Google adsense to show up.
