Mobile traffic from iPhones

Hi everybody! I search for a mobile CPC traffic, but have some specific needs: it should be from iPhones only, US geo and there should be a possibility to adjust number of clicks provided per hour. I allready use trafficholder, but not completely happy with it recently, need an alternative.
Does anybody know where this can be got?

Traffic holder is perfectly works for me. So I didn't know any alternative method.

I agree with you, that it is almost perfect. But sometimes it forces to increase payments too much to deliver needed traffic volumes, especially recently

Maybe you can get some from ultimatewebtraffic or traffmagic? You can always check and see if they have what you need.
