Pre key sounds

[corbyphillips]

Hello Precentral. I have a question about the Pre, and if it can be done, I'll ask you all for help. But firstly, I wanted to ask: Because my cousins IPhone was able to have his key tones changed, is it possible to do it on the pre? What I mean is, when he has his screen locked and needs to type in a password, it makes the sounds from Metal Gear. Though not just that. Everything he touches on his phone makes some sound affect.
