Is it possible to change font on iPhone if you have updated to iOS 9 firmware? Those users who are running iOS 9, iOS 9.0.2 or iOS 9.0.1 are able to complete this task. It is possible to add changes to your system font on both iPad and iPhone if you are jailbroken. It is possible to jailbreak iOS 9 – 9.0.2 using Pangu. Unfortunately the program doesn’t support iOS 9.1 jailbreak so you cannot use the same iOS 9 system font change instruction if you have installed 9.1 version already. You can’t also downgrade from 9.1 to 9.0.2 any more because Apple doesn’t sign this system. How to Change iOS 9 System Font iPhone Guide
