I guess this is the firs of its kind. Obviously it was only done to showcase the fact that the Sony Xperia Z3 is waterproof.
I wonder if the charger is waterproof too.
By they way, I’m not sure if I have said that before in here. If it wasn’t for the iPhone and iOS I would probably choose one of the high end Sony Xperia phones or a HTC. They look good.
