Opera just announced the launch of Opera Mini 5 for J2ME and Blackberry along with Opera Mobile 10. These are final releases as Opera Mini 5 was previously available as a beta. It includes features like Tabbed browsing, Speed dial and a bookmark synchronization system called Opera Link. On some platform, Opera Mini 5 is much more efficient than the default browser – particularly on Blackberry phones. I tried it with a Blackberry 9700 Bold and Opera Mini 5 trounces the default web browser. Opera Mini 5 is available for Java phones, Blackberry, Android and Windows Mobile.
While Opera Mini works on many phones, including basic ones, Opera Mobile 10 is designed for more powerful smartphones. It features Opera Turbo, a technology that offloads the web page parsing and loading from the smartphone to servers hosted by Opera. This results in less network transaction to retrieve web pages, which is a win for the user and the wireless carriers as it contributes to decongest cellular networks. Opera Mobile 10 has just been released for Windows Mobile and Symbian. Head to m.opera.com to download from your phone
