Nokia S60 WebKit
Nokia have released the source code for S60 WebKit. This is a super-set of the source already available at opensource.nokia.com.
This new release is provided in a way such that developers can extend or contribute to the S60 WebKit project. There’s even a ‘Reindeer’ reference browser UI that can be used to create derivatives of the S60 browser.

Dig deep into the source and you will even find an (unsupported) S60 Internals WML engine!
Nokia have some suggested ways in which developers can contribute to the project …
-
Reindeer SISX builds via the GCCE compiler
-
Porting S60WebKit to S60 2nd Edition
-
New testing frameworks, such as the Mozilla test suite
-
Version upgrade automation systems
-
Performance enhancements
-
Python API
-
Scriptable UI
