Opera Mini 5.1 is a hugely successful mobile browser that has already launched on Android and BlackBerry smartphones and it is now available on Windows mobiles.

Users with Windows Phones running on Windows Mobile 2003 SE, 5 series and 6 series versions  of Windows Mobile can now download the browser.

The key to Operas success is the increase in speed and reduction in data traffic that Opera brings by first compressing web-pages on its own servers before sending them to your mobile. Opera Mini 5.1 brings this capability to Windows mobile,  as well as enabling support for high-resolution mobiles.

Additionally, it  improves the page layout and font, adds support for mobiles that have auto-rotation  and provides configuration support for power users. You can also set Opera Mini as the default browser on your Windows mobile with the launch of Opera Mini 5.1.
