The idea is pretty simple, you upload an image and the site does all the hard work for you, whether you choose a photo or some artwork is entirely up to you, however for best results you must use a pretty high resolution image (1650 x 1650 or above is recommended).

Once you have uploaded an image there’s lots of things you can modify, firstly not only can you create the custom case for the iPhone 4 and iPhone 4S, but if you want you can create a case for the iPhone 3G, iPhone 3GS, iPod Touch 4G, Samsung Galaxy S Vibrant, BlackBerry Bold 9900, BlackBerry Bold 9700 and the BlackBerry Curve – all of which cost $34.99 – that said the iPhone 4 / iPhone 4S case is also available in a “Tough” variant which will cost an additional $5.

Now that you have chosen your device, case type and uploaded an image you can change the image’s positioning, rotate it and even change the level of magnification. I had a quick play and my un-artistic eye managed to come up with this case:

As you can see the cases should turn out pretty good if you take your time and ensure you use a high-resolution image to start with, that said you can alternatively select art from the gallery which you can then further customize.

When compared to other pre-designed cases the price is a little higher, but we think that you can’t really put a price on a completely unique design – so head over to Case-Mate to design your own case!
