How do I install Opera for windows phone 7.5 in my mobile

Hi

I am missing opera a lot in my new windows phone running windows 7.5 mango, it has internet explorer, it works fine but its not as customizable as I see opera for mobile.

I tried marketplace but there is no other browser, there was a browser named cube but is useless.

Go to m.opera.com from your mobile browser and check there if any windows version is available
