Several months ago, we showed you how you can change the iPhone’s system font using FontSwap. BytaFont, which is a free app available on Cydia, provides an alternative way to customize the system font and it offers even more font choices to choose from.
BytaFont lets you change fonts on any iOS devices including iPhone and iPod touch running iOS 4.0 (or up).
To use BytaFont, you need to have a jailbroken iPhone. If you already have one, simply launch cydia, search for “BytaFont” and install it. The app is just a font selection font. It doesn’t come with any fonts (except the original system font of iPhone). You need to go to the “Font” section on Cydia and download the fonts.
