To add to xiaolong's comment, apple devices hard cap their fps to the display's refresh rate so it will not show any fps above 60 even if this glitch is patched for his iphone. Nonetheless it is true that changing the vsync settings in the options.txt file to 0 does not allow us to have more than 60 fps on devices with a 120Hz display.
