Case-mate's cases enable customers to choose their own logos, designs, or images that will be tailor made for their specific smartphone. Currently, these DIY custom cases can only be made for popular smartphones like the iPhone 3G, 3GS, 4, and the BlackBerry 8520 and 9700. Although you can always side with choosing some sort of generic image, you can upload high-resolution images that tally in at least 1650 x 1650 to make them look visually stunning when it's transitioned onto the case. In addition, customers can also choose the placement of where the image is going to be positioned on it.
For $40, you can get Case-mate's Hybrid Tough case to add some additional protection for you handset, while their $35 Barely There case can just make your smartphone look good.
