CAUTION:read completely before doing anything
Take any font in your computer that is nice for mobile(double click on the font file and check size of font on size12 it should be small for mobile eg. check asgasansbold.ttf attached here).Or you can find fonts in C/windows/fonts. copy any to a temp folder(you should drag and drop any font to another location and make a copy and drag the font back to original folder),make four copies of it in new folder,or repeat using new fonts.
now take usb mode in mobile and connect to pc,and copy the fonts to E/resource/fonts after renaming them as what you see in c/resource(or system)/fonts.you should rename as nohindisnr60.ttf,nohindissb60.ttf,nohinditsb60.ttf ,S60ZDIGI.ttf(four files like that).now remove the phone from pc and restart the phone for fonts to take effect.
now you cannot use the usb mode(cause fonts are on card) and phone will be a little slower(cause fonts on card),but the only thing fonts make the phone look different
to remove the fonts u should have phone that can put memory cards while the phone is switched on.On the phone without the card,and then insert the card and delete the fonts using usb mode or file explorer.for phones that insert cards under the battery,please use card reader and delete off the fonts
Attached here are two fonts,asgaboldsans is tested on n82 and is good.
