Opera Mini, everybody's 'go to' web browser on Symbian when there's the slightest whiff of a shortage of bandwidth, has had a major update, from 7.03 to 7.10, screenshotted below. Aside from UI tweaks and optimisations, the major thing here is better download management. Note that there have been server-side fixes too, including fixing the (very low bandwidth) YouTube video streaming.
You can grab v7.10 by pointing Web on your smartphone to m.opera.com. Here's installation and shots of the new version of Opera Mini in action:
Installation - the top link is the one you want...
The Start screen, here remembering my configuration from a previous version, it seems(!); (right) AAS loaded up
The mobile and full desktop versions of IMDB rendered in Opera Mini - as usual, you can pan around and pinch/splay to zoom as needed
Rendering the full monstrosity that's The Verge's desktop site - it loads faster than on my desktop (due to the server-side compression, etc.); (right) YouTube and other streaming video is handled by the server grabbing and transcoding the stream - the end result is 240p at best, but it does provide a way to watch YouTube content and make sense of it even on a slow 3G connection.
