The Verizon G4 allows you to change the Font (Settings-Display-Font Type), however it only lets you choose from a half dozen fonts. I extracted the Smart World app from my International G4 (H815) and was able to install it on my Verizon G4. After doing so, there will be a "+" sign in the upper right of the Font change screen, letting you add fonts.
This was tested on the Verizon G4. If other variants also removed this option, then the above method might work as well.
P.S. I was able to install themes with the Smart World app, however, I could not apply it to the G4 using the hidden activity method like on the G3.
