Advertising is coming to the iPhone

In the new iPhone OS 4.0, you'll start seeing advertisements on your mobile device. Google's Android already displays ads. I'm guessing that Windows Phone 7 will also have the capability for ads. Isn't amazing how we simply can't avoid advertisements? I sell ad space on my sites. Almost every medical publisher does as well. I just hope that these ads may fuel the availability of more free smartphone apps and smartphone services for medical professionals.
