Jailbreak
The first step in being able to cheat in "Need for Speed: Shift" is to jailbreak the phone. Jailbreaking is a process that allows the phone to download apps different from those normally offered by Apple. It is not illegal to jailbreak an iPhone; however, it does void the warranty on the phone and brings about the possibility of downloading malicious apps. The easiest way to jailbreak an iPhone is to simple use the browser to visit "jailbreakme.com." Once the site is loaded simply slide the arrow across the "slide to jailbreak" bar and wait for the process to complete. If at anytime you wish to un-jailbreak the phone simply connect it to a computer and use iTunes to restore the phone to its default settings.
Cydia
The most widely used, trusted and available program for downloading software packages on the iPhone is an application called Cydia. This program is needed in order to enable the money cheat on "Need for Speed: Shift." Once the iPhone is jailbroken, locate the Cydia application on the iPhone main menu and enter the program. Select "User (Graphical Only)" to install the application software. The entire menu of Cydia packages is now available on the phone.
