Everyone used to jokingly say that the iPhone can pretty much do everything, but I think we're slowly eating our words, as devices like this Dock Fan for iPhone prove the touch-screen phone can pretty much handle any task.
The Dock Fan is an add-on that's akin to those fans kids used to buy at amusement parks each summer. Simply plug the foldable fan into the iPhone and watch as the Apple device powers the Dock Fan with its lithium battery. The fan itself only costs $15, and to top it all off, it comes in a mini carrying case that looks like an iPhone!
I've got to say, if I'm ever caught outside on a hot day, I'd definitely wish I had one of these things, even if it was draining precious hours away from my music listening.
