You may remember that Opera Software recently ported their acclaimed proxy-based web browser to (native) Symbian? Beta 1 of Opera Mini 5.1 was great apart from some weirdness when it came to incorporating text input from the phone's own text input system (e.g. virtual keyboard). Now we have Beta 2, with this fixed and doubtless a multitude of other minor bugs quoshed.
You can grab Opera Mini 5.1 beta 2 for Symbian most easily by going to m.opera.com in Web on your smartphone. It'll work with any Symbian-powered phone from the last three or four years. Recommended, especially if you're conscious of data use and have been wary of many of the larger, more bloated web sites on the 'net.
