While 3D has hardly lit up the world of tech, iPhone users hoping to enjoy the extra dimension will be pleased to know the capability is now available thanks to a case with a lenticular screen cover. Glasses not required.

The 3D Movie Viewer Case from Deal Extreme might rock up in a baby-pink and black design, but it'll mount on the front of the iPhone 4 so users can view specs-free 3D vids.

Of course, you'll have to download the content first, and find an app that'll play it. Fortunately - or not - the case comes with a bunch of 3D demo files on disc, with a "random movie" thrown in.

So if you wanna turn you're iPhone into something a bit more HTC Evo 3D or LG Optimus 3D, then visit Deal Extreme, where they're available for $23 (£14) a pop. ®
