Before, the only mobile browser I knew that could render adsense for content fully is Bolt Browser which is also a java based browser like Opera Mini but with a more desktop-like browsing experience.
It's rather a good news that Google Adsense for content which is javascript based now displays on mobile browsers like Opera Mini. There are lots of visitors using mobile devices and this definitely means increased CTR.
I hope this javascript based ads will also be extended to Adsense for mobile since javascript based mobile ads is only presently availabe for iphones and other high end Android smartphones.
UPDATE - 28th June, 2011
Google has since disable this. The ads stopped showing on opera mini barely ten days after this post was made. Perhaps they realized there was increased CTR which means they were going to pay more than they usually do. lol
