The world of online marketing has just been notified by Google that Flash ads will begin appearing on the iPhone and G1.  According to Google, they will now begin detecting if either browser is being used and if so they will adjust their ads to fit the device.  For advertisers this allows highly-targeted ads for Android and iPhone users and even other devices that have full HTML browsers. Recent changes to Google’s mobile results pages mean that ads should be easier to read and format correctly on handheld devices.  If you thought you could escape the world of advertising on your mobile, you are only seeing the tip of the iceberg.
