Ovi Browser is a new browser for Nokia Series 40 (S40) devices that aims to provide an easier, faster, and cheaper browsing experience. It uses various technologies like server-side compression and a proxy server to reduce data usage and speed up page loading. Some key features include a localized start page with popular local content, search and favorites tabs for simple access to searches and bookmarked pages, and different viewing modes. The beta version is available to download now on over 20 S40 handsets to try out these capabilities and improvements for mobile browsing.
