Opera today unleashed the final version of Opera Mobile 10.1 for Symbian/Series 60 phones, with significantly faster JavaScript performance.

Making its debut in Opera Mobile 10.1 for Symbian is just-in-time compilation (JIT) performance optimization to the Carakan JavaScript engine, the same engine that drives Opera's desktop browser. Speed trials of today's release show that Opera Mobile 10.1 races ahead of its predecessor, performing nine times faster than Opera Mobile 10.0 on the SunSpider JavaScript test.

Also making its debut in Opera Mobile 10.1 is support for geolocation, which puts you and your mobile on the map. Geolocation enables web services such as maps and travel applications to recognize your location to provide you with customized, relevant content.

Opera Mobile 10.1 also features:

- Speed Dial, tabbed browsing, Opera Link and password manager - reduce the time and typing required to navigate your favorite websites.
- When slow network speeds put the brakes on your browsing, gear up with Opera Turbo compression. Opera servers shrink webpages to as little as 20 percent of their original size, reducing your data costs and turbo-charging your browsing speed.
- Opera Mobile fine-tunes the look and feel of your browsing with kinetic scrolling, a virtual keyboard and auto-rotation to landscape.

Opera Mobile 10.1 is available for smartphones based on Symbian^3, and Symbian S60 3rd and 5th editions. Opera Mobile is free to download from m.opera.com.
