Opera have announced availability of their Opera Mini 4.1 beta, the newest release from the browser company.  Available in Java, Palm and BlackBerry versions, the browser is apparently 50-percent faster than previous versions while maintaining the same bookmark sync between different versions of the software on different platforms, portrait & landscape modes, and custom search shortcuts. 

Check out the demo video of Opera Mini 4.1 beta after the cut 

Other than the speed improvements, the beta version also features:

• Autocomplete your URLs - Opera Mini will automatically suggest URLs as you type
• Save pages
• Find content on the page
• Download and upload files
