So here’s the method for using iFacePad, though for now at least, it’s Mac-only.
Download the app – iFacePad
Get hold of iOS 4.2.1 for the iPod touch, 4th generation from here.
Download PhoneDisk
Jailbreak your iPad on 4.2.1 (tethered, untethered) – but you did that already, right?
Fire up Cydia on your iPad and install OpenSSH and AFC2 (AFC2 is installed by default if you used GreenPois0n)
Run PhoneDisk, enable Root and connect to it.
Run iFacePad.app and reboot.
Call someone!
That should get you up and running, but if you do find iFacePad doesn’t launch then check the permissions are set correctly for
/System/Library/PrivateFrameworks/IMcore.framework/IMAgent.app is set 755.
One word of caution – just remember they won’t be able to see you. That’s not always a bad thing though!
