Sorry, that's not a browser, it can't even run Javascript. It is basically a web proxy.

From http://en.wikipedia.org/wiki/Opera_Mini Unlike ordinary web browsers, Opera Mini fetches all content through a proxy server that reformats web pages into a format more suitable for small screens.[32] A page is compressed, then delivered to the phone in a markup language called OBML (Opera Binary Markup Language).

Browsers like Firefox and Opera Mobile are explicity banned by Apple.
