Darla Mack has written a nice tutorial on how to change the defaults fonts on Nokia S60 3rd Edition based N-Series/E-Series mobile devices such as Nokia N95, E60, N93, N80 etc to that of a Windows Vista or XP based computer. Windows Vista has introduced some nice, large fonts about which I had talked about earlier in the Guide to installing Windows Vista/Outlook 2007 Fonts on Windows XP/Outlook 2003.

Here’s a brief step by step on how to go about doing the same on your S60 mobile device:

1) Goto to Start—>Run and type Fonts. It will take you to the C:\WINDOWS\Fonts folder which contain all your system fonts
2) Create a new folder on your desktop called Fonts
3) Copy TTF fonts from C:\WINDOWS\Fonts to the Fonts folder on your desktop
4) Rename the Fonts on the folder on your desktop to match the names of the preinstalled Fonts on your mobile device found under Z:/resource/fonts (Z: is your Flash ROM) such as:

nosnr60.ttf = Nokia Sans S60 Regular
nssb60.ttf = Nokia Sans S60 SemiBold
nstsb60.ttf = Nokia Sans S60 TitleSmBd S60
S60ZDIGI.ttf = Series 60 ZDigi

5) Connect your mobile phone in the Mass Storage mode to the computer or use a card reader to access your memory card (E: drive)
6) Copy the Fonts folder from your desktop to the E:\Resource folder on the memory card. If you get a file copy or in use error, try copying the folder using a USB card reader.
7) Change the mobile device mode to PC Suite, unplug it and reboot the phone

If you want to undo this, simple remove your memory card, reboot the phone, delete the Fonts folder from E:\Resource folder and put it back again.

Warning: Do this at your own risk
