Opera Software has unveiled new versions of its Mini and Mobile wireless browsers with improved scrolling, panning and zooming features.

The new browsers feature pinch-to-zoom function and a share button, so you can easily post, Tweet, or share information on Facebook, vKontakte or My Opera, the company said.

The new versions are also optimised for tablets, to bring smooth browsing on a tablet PC with a new upgraded interface.

Opera Software CEO Lars Boilesen said if you’ve lost that loving feeling for the Web on your phone or tablet, don’t let it bring you down. "Just try one of our browsers."

Opera said its Mini browser uses the company’s servers to shake, rattle and roll webpages down to a tenth of their original size before sending them to your phone.

The Opera Mini 6 browser is compatible with J2ME, Android, BlackBerry and Symbian/S60 phones.

Opera’s mobile browsers are used by more than 100 million people worldwide, on more than 3000 devices, the company said.

The browsers can be downloaded to a phone by going to m.opera.com.
