Opera Mobile 10.1 for Nokia smartphones goes final
Dag Norem from the Opera Mobile blog summed up some of the downsides like the lack of Flash support and pinch-to-zoom, as well as higher memory requirements. The native browser on Nokia phones like the N8 supports Flash Lite, but many users find its performance sub-par when it comes to speed, while Opera Mobile 10.1 manages to run very smoothly.
Opera Mobile 10.1 is available for smartphones running Symbian^3, as well as Symbian S60 3rd and 5th Editions. Let us know which browser you prefer on your Nokia!
