Genuinely wouldn't surprise me to see a Gameboy emulator for it one day, pokémon on your phone anyone?
It won't happen, because that sort of thing wouldn't make it past the selection process for the App Store, which is one place where Apple's DRM policy fails. You see, it isn't a particularly big step forward to have a Game Boy emulator on a phone; my Palm T|X, first produced in 2005, can not only emulate the NES and Game Boy, but can also, with additional software, emulate the SNES and Mega Drive as well. Older Palm OS devices can do it as well.

You see, this is possible because most mobile operating systems aren't restricted in the same way that the iPhone OS is. The iPhone's OS is horribly restrictive, lacks multitasking and is coupled to a device that's decisively crippled.
