Google might be preparing for the launch of the Android powered G1, but they are still very interested in the iPhone and a user base that will top 10 million by year's end. Being the default search engine for mobile Safari has a potential to be a money maker for Google and now comes word they are going to start offering options for advertisers to target iPhone owners directly.
Google has met with a number of ad agencies and shortly, they will be offering a new option to show an iPhone specific ads as part of a companies search campaign. While the iPhone has the capability to show the full Internet, the ads would be mobile specific. For example, and American Airlines ad could have a click to action that would call to book a flight.
