Also, there has an update about the speed of the browser, as Opera Mini 4.1 is said to be able to receive the requested Web pages up to 50% faster.
On phones with JSR-75, users can now upload and download files using Opera Mini 4.1, without being re-routed to your phone’s native browser. This might come in handy for anyone looking to update his blog or his photo gallery on his site or social network. The same principle applies for email attachments.
Another feature also aimed at phones with JSR-75 will enable Opera Mini 4.1 users to save pages for offline viewing, so they can access and read the desired Web content, no matter their location.
Opera Mini 4.1 can be downloaded from here.
