PS3 Controller Bluetooth Connection to iOS Device?

Hey guys I have done a little research on trying to connect a PS3 controller to my iPhone 4 via a bluetooth connection but the closest i have come to this is an app in the jailbreak community title "BTStacker."

I know the interest is there but has anyone had any luck actually pairing the two? From what i have gathered it is not possible as of now to actually have the controller communicate to an iOS device although i do not know (technically) why. Can anyone explain or give me any information and perhaps a solution to this problem? I think the demand/interest for console controllers to be able to pair to our iPads and iPhones is extremely high, but are there any developers in the jailbreak community actively pursuing this?

Thanks for the help guys any input or discussion is greatly appreciated.
