Nokia have a history with hydrophobic technology for their phones - but they're also planning to take the technology beyond the concept stage and bring it to all future Lumia and PureView devices and make them waterproof.
Unlike current waterproof phones whose outer shell keeps the water out, Nokia plans to coat both the outside and the inside with the stuff, so even if water gets inside the phone it won't do any damage.
'Nano technology lets us do it. Superhydrophobic technology makes water bounce, it stops it, rolls it off the device and leaves it water impregnant, that's the magic, that's what we're going to bring to the third party.
Nokia's intention with this technology is to implement into all future PureView and Lumia devices. Waterproof phones have been called for since time immemorial, but it's only recently that handsets such as the Motorola Defy Plus have effectively managed to combine quality with solidity in a phone.
