Step 1: Install the FontRemover.sis to your mobile. Once installed, launch the application and it should ask you if you want to delete font. Click on Yes and it should tell you to reboot your mobile. Do not reboot yet.

Step 2: Now send one of the font in GDR format to your mobile, let’s say comicbold-lovekonadj.gdr. You can send it through Infrared, Bluetooth or copy it using Card Reader. Take care do not install it.

If sent via Infrared or Bluetooth a message will come to you. Do not open or delete the message. Go to the drive where your messages are stored (C: for Phone Memory & E: for MMC). Browse using some file explore to the path like following (Here X is your message memory drive).
X:\system\mail\00001001_S\0-9, a-f
Look for the folder that contains the GDR file you sent. When found, copy/cut it.

If copied using Card Reader, simply copy/cut the GDR file using the file explorer.

Do not exit your file explorer yet. Now, follow step 3.

Step 3: Go to C:\system and create a folder named "fonts" (without the quotes), i.e. the full path should be:
C:\system\fonts
Paste the GDR file you copied here.

Step 4: Exit file explorer and reboot your mobile.

When the phone boots again, you should see the new font.

NOTE: You need to understand that you can only use one font at a time. If you want to use another font, you will have to follow steps 2 to 4 of above procedure again.

If you want to restore your default font, just launch the font remover and click Yes when asked to delete font, and reboot your mobile without doing steps 2 - 4.
