Typing symbols or pictures on the iPhone just got easier thanks to a Cydia tweak called PictoKeyboard. The free software package temporarily replaces an unused international keyboard with unicode symbols that can be typed anywhere. Many of the symbols are similar to emoji icons, which can be installed without jailbreaking.
If your iPhone is jailbroken, the installation of PictoKeyboard takes place in just a few steps and provides an easy way to add unicode symbols including the ever-popular Apple logo. Additional symbol keys can be accessed using the numerical keyboard or pressing the shift button.
