I've done a fair bit of programming for Symbian mobile phones. Mainly for the semacode project. Here's some free advice/ documentation of stuff I've done.

HOWTO develop Symbian apps using Mac OS X - explains how to install a working development environment for Symbian C++ on Mac OS X.

HOWTO launch a browser from Symbian C++ - it's not as easy as it should be. This is basically code you can use.

Unpack Nokia's Symbian Series 60 SDK 2.1 on Linux/Mac OS X - this makes an exceeding difficult process fairly easy.
