please i wana theme

For one, you can try making one yourself: Start by downloading the "Series 60 Theme Studio" application from http://forum.nokia.com (read the "Series 60 Theme Studio Artist's Guide" first).

Or, you can check if there's already a theme you like on http://www.symbianthemes.com/ (if you haven't already). There might also be a commercial theme on, e.g., http://www.mangothemes.com/
