Opera Mobile 11.1 also has some additional features including what the company calls "experimental support" for Adobe Flash on tablets running Android 3.x Honeycomb. Also improved is support for HTML5 and the rendering engine has been upgraded to Opera Presto 2.8.149. A complete changelog is available from the sourcelink.
In case you are wondering about the difference between the two Opera browsers, Opera Mini is for slower phones and uses a remote server to download your site which is then (up to 90%) compressed and sent to your phone, saving you time-and if you pay for data-money. Opera Mobile is for faster devices and renders the web page directly from your phone. Both are available for free from the Android Market for devices running Android 1.6 or higher.
