Among the gigantic number of cellphones coming out these days is the Gionee S20, a slider from China which comes equipped with a NES emulator. Other than that there is a 2MPx sensor, TV output (play NES games on your TV from the cellie) and the usual video and audio codecs compatibility. Last thing to do is downloading ROMs and sent them to the cellphone.

Pretty good idea, I wonder how long before we get a ZSNES phone?
