With iFonts Book, you can see all the fonts available on the iPhone.
In the app youll have a whole list of fonts family (regular, bold, italic etc.).
When you press on one of the fonts, youll be able to see the whole alphabet in lower and uppercase and the numbers from 0 to 9 in the selected font.
Youll also be able to change the text in the fonts itself and to change the fonts size too.
Enjoy!
