Today Opera Software announced a new beta version of the Opera Mini browser. The 4.1 beta offers a number of improvements, including up to 50% faster page loads. It also automatically suggests URL completions and lets you immediately find the content you want with a new search feature. Opera Mini 4.1 will let you save web pages so they can be viewed when the phone is offline, and it can now be used to manage uploads and downloads from and to your phone. The beta version is free to download and use.
