It's mostly already there... turn on parental restrictions, block/disable all default apps except those, and then have a friend set the parental restriction code to something you don't know.
I'm sure Apple would just say "you don't really want an iPhone, then" as a response.
They want a 3310 and a separate camera.
I'm not sure what your point is, because a phone without a QWERTY keyboard or full-size screen isn't comparable to an iPhone...
