Hot off the presses: Nokia introduces a new Web browser for S60 3rd Edition:
"The browser's open source codebase and extensible architecture will enable other industry parties, such as S60 licensees and the open source community, to develop new features for the browser. S60 application developers can use open APIs to build on top of the browser, using it to render rich content within their application. Nokia is committed to open source, and intends to actively participate in the open source community to further develop and enhance the browser, contributing Nokia's expertise in mobility."
"...the new Web browser for S60 is based on the WebCore and JavaScriptCore components of Apple's Safari Web Kit..."
