Regardless of whether or not you think the iPhone 4 is the best/worse mobile phone in the world, you've got to love this retro sticker cover created for it by a gaming fan.

If you hadn't already worked it out, it's of the original Tetris-loving Gameboy handheld console.

Created from a design by some dude called Vinh, and then turned into a Gelaskin, you stick it on the back of your iPhone, not the front, to give your phone of today the technological look of yesterday.

The good news is you can buy the design through Zapstatic, and if you haven't got an iPhone 4, don't panic, you can also get a 3G or 3GS model as well. 

Yours for 10 bucks.
