The problem with Nintendo developing for cell phones is that they would have to make phones for all the different cell carriers with acceptable controls like their own mobile systems. Using just a touch screen is awful for the type of games that are usually the best on Nintendo mobile systems. Sure they could make a Bluetooth game controller for cell phones, but at that point you're carrying 2 things with you, and not really better off than just carrying a 3ds.
I've played Mario kart through my phone (snes emulator) using the touchscreen, and it's just not fun. I'd much rather pull out a dedicated game system to play
