Uniea's U-Feel is a touch-through case similar to Case-Mate's Naked Case. The differentiating factor here is that the U-Feel has a colored backing and a removable belt clip which doubles as a kickstand for propping up your iPhone.
This case by Orion Gadgets is simple and flexible. A cheap alternative to purchasing more expensive iPhone cases, this silicone sleeve is inexpensive and easy to apply.
