Some Nokia sets feature similar-sized headset and charging jacks and in an effort to help owners quickly tell them apart -- and prevent potential damage to the handset -- Nokia may have decided on a bit of clever gadgetry to save the day. The idea is dead-simple, one port will be positively magnetized, the other negatively, so if you try to plug in your cables to the wrong place they will repel. Safe and simple, we like it, now if they were able to extend it out to some type of MagSafe charger adapter.
