Opera, the other alternative browser (and a darn good one) discusses how mobile operators are making money using the Opera Mini browser.  Mini was designed specifically for mobile phones, their small screen, and their keypad.  Their press release yesterday gives a lot of detail on who is using it and how its being used.

Russell Beattie has a nice post on this topic as well.  By the way Russ, nice new layout – kind of minimalistic, I like it!
