Check out this letter sent to The Register by someone saying that back in 2001 they were working on a prototype of device that could connect a Gameboy Advance to cellphone to let people play wireless multiplayer games and use the GBA as a phone. They say they even approached Nokia and Siemens about working together, proposing that it’d be easier to piggyback on Nintendo’s success rather than try and build a new brand from scratch. Neither company was interested, and of course, as we all know by now, Nokia introduced its own N-Gage gamephone two years later.
