However , When you request a page in Opera Mini, the request is sent to the Opera Mini server that then downloads the page from the Internet. The server then wraps up your page up in a compressed package (Opera call it OBML), and send back to your phone Opera Mini . (For more details http://www.opera.com/mobile/specs/ )
Thus Opera mini is not the browser working on your phone but on the Opera Server. Hence your Phone does not get authenticated .
Thus you can use any other browser (Opera Mobile , Chrome , Safari or Native ) which will work but not Opera Mini .
