Opera has launched new versions of its Mini and Mobile web browsers at the MWC today: Opera Mini Next and Opera Mobile 12. Opera Mini Next is actually a preview of what’s coming in the next version of Opera Mini, the company’s browser that works on Java-supporting feature phones and smartphones.

It brings Facebook and Twitter integration through something called Smart Page, a starting screen that gives you easy access to social networking functions, news and other goodies. The Smart Page won’t appear in the smartphone version of Opera Mini Next, though. There, users will get hardware acceleration and a revamped speed dial, which now features an unlimited number of Speed Dial shortcuts.

The company’s native smartphone browser, Opera Mobile, has reached version 12 for Android and Symbian devices. It brings WebGL support, which should make it easier for developers to create and distribute cross-platform games. It also supports Opera’s HTML5 parser Ragnarök, more Speed Dial customization options as well as support for camera use in the browser.
