Sporting a redesigned interface reminiscent of the previous version. I haven't tried Opera Mini yet but Opera Mobile worked very fast for me on a weak Wi Fi connection loading full version webpages in mere seconds with smooth scrolling.

I installed it last night (the Mobile version), and it was absolutely appalling, even over WiFi - I was frantically swiping the screen and zooming in and out to no avail. It was dog slow!

For some reason I tried it again today, just over HSDPA here at work, and it was as smooth as silk! Lucky I didn't uninstall it, as I quite like the Opera UI - it was always my favourite on the i8910.
