Opera Mini 4.1 beta was released today. Opera is a fantastic browser and it's mini incarnation is the best mobile browser I have ever used. The new beta release has some new features:

• Auto-complete of web addresses, based on previously entered addresses and bookmarks
• Uploading and downloading within Opera mini without relying on the device default browser
• Save pages locally for fast retrieval later

And the Opera team have significantly upgraded their infrastructure, and claim that pages will be delivered 50% faster than previously. So far I can vouch for the faster performance.

I reviewed version 4 a little while ago and gave it a thumbs up. Read it here if you are interested in trying a mobile browser. Grab the beta here.
