Samsung today announced the L870 Symbian-based phone. Interestingly, spec sheets obtained by phoneArena.com (via Engadget) specify that the phone uses the Safari web browser.
The default web browser of the S60 platform is indeed a WebKit-based browser developed by Nokia. The "Safari" designation, however, would seem to indicate some cooperation with Apple, as Safari is an Apple-registered trademark.
Regardless, the move appears to be yet another win for the Apple-supported WebKit rendering engine. Recently, Adobe has announced that the Air platform is utilizing WebKit, and Dreamweaver CS4 will be using WebKit for its Live View feature.
