AdSense for Mobile Now Supports High-End Handsets
It seems that high-end mobile phones with full HTML Internet browsers are growing more popular by the day, iPhone and Android devices included, so Google had to capitalize on this trend. They went out and announced a new feature for AdSense mobile publishers, allowing them to take advantage of the high-end mobile browsing experience.
Also, this improvement allows users to select additional ad unit sizes, from AdSense formats. If the user is targeting all mobile devices, he won’t need to update his AdSense code for larger ads, since Google will automatically detect the settings and serve a larger ad.
