Mozilla already had launched a web-browser for mobile devices. Skyfire is a very fast browser i couldn’t compare it with Opera mini ( The mobile browser from Opera) but it is good.
It lets you watch videos , listen to music and ya surf the web as well.
What i believe it’s made for good multimedia phones with enough RAM like the HTC touch phones and Nokia’s E and N series phones and for similar phones as well. See the Demo Video
