Yes, you read correctly, over at CultofMacthey reported on finding Apple had a newly-published patent application which not only just makes the phone waterproof it actually repels water using electrode technology to actively expel water that has become trapped in the device, rather than just fighting to keep it out. 

The device would detect liquid, Electrodes would then be used to move the drops of liquid toward an exit point, where it could be safely expelled from the iPhone.
