Iphone sounds

I was wondering it anyone has the original Iphone sounds that it shipped with.

In iBricker I changed the sound of the lock and unlock screen action to a cool PC voice saying "activated" which is neat, but I couldnt find anywhere ont he Iphone the original sound so i could copy it should I want to restore it

So I'm wondering if any of you clever guys have figured out a way to pull the sounds off so you can always revert back to them without having to do a full system restore
