How do you connect ps3 controller to an iPod touch without jailbreak?

To connect a PS3 controller to an iPod Touch without jailbreaking, you will need a Bluetooth adapter that supports the controller, as iOS does not natively support PS3 controllers. First, ensure the controller is in pairing mode by pressing the PS button and the "Share" button until the light bar starts flashing. On your iPod Touch, go to Settings > Bluetooth, turn on Bluetooth, and wait for the controller to appear in the list of devices. Tap on the controller to pair it with your iPod Touch.
