"Many of the get-rich-quick iPhone stories we've seen involve small development efforts -- one or two people -- selling enough apps for $1 each that they can quit their day jobs and work on iPhone stuff all the time. But some companies are also making a nice amount of revenue from in-app ads, according to one iPhone ad firm. In a report (embedded below), AdWhirl says that top apps can make $400 to $5,000 per day on ads, averaging an effective CPM (cost per 1,000 impressions) near $2."
