To manage the fonts that your phone uses, you’ll need two applications. The first, FontRouter LT, will need to be signed. You can either use OpenSigned to do this, or you can hack your phone. The second app, FontRouterMan, is already signed, and provides an interface to the changes that FontRouter LT makes to your system. Once you have installed both applications to the memory card of your phone, you can then install fonts easily. I have tested both applications on the Nokia N79, E63, and 5800 XpressMusic, so you shouldn’t have any trouble installing and using them on your phone.

You can use any .ttf font on your Symbian-powered smartphone, but make sure that the extension is ‘.ttf’ and not ‘.TTF’. (I had no problem using .TTF).Apparently, there is a difference, as I discovered. You can  then simply use any file manager (including the built-in one) to put the font files in E:/data/Fonts on your phone.
