Cold hands? Hot gadget

It's the gadget you've been waiting for, the one that allows you to talk about your two favourite topics of conversation – the weather and your iPhone – at the same time! Yes, it's an iPhone app that keeps your hands warm. It heats up your phone by turning it up to 100% of its power processing capacity, apparently, and you can control exactly how hot it gets with a little slider thingy on the front. Ingenious! Unless, of course, you forget you've turned the heat up and hold the phone to your ear when someone calls. We're sure they've thought about that. And we're not sure how long Monkey's handset would last at full power. Seven minutes? Yours for just 59p. Also available: gloves.
