Japan cellphone giant, NTT DoCoMo, has developed this Nintendo Gameboy Advance SP-looking cellphone. This phone actually includes the solar cells on the external side of the clamshell—therefore not needing any other devices to use the sun's rays to charge. On a side note: this would be great for those of us that constantly forget their cellphone chargers regularly (I'm home for the holidays and I forgot mine again, damnit!).
