If you love how slim your iPhone 4 is and want to keep it that way but still need protection, then you might want to look at Case mate's Gelli case. The Gelli case is a TPU case that is so slim, you won't even know you have it on. Unlike other TPU case out there, the Gelli is much more flexible and very easy to put on, hence the name Gelli. The Gelli features vibrant, semi-transparant colors and patterns which show off the back of your iPhone 4's Apple logo. Because of how slim and thin the Gelli case is, it won't be a good drop protector, however it will do great protecting your iPhone against scratches and light bumps. The cutouts on the Gelli case are perfect with easy to press buttons. There is a nice lay out the table front lip so that you don't need to worry about your screen to much.
The Gelli case overall is a simple, slimline case for the iPhone 4. It's a great case for those who seek such a case for their iPhone. The Gelli doesn't feel like it's made from a high quality material like the iSkin Solo, however for the price it isn't bad at all. The Gelli comes with one screen protectors, a cleaning cloth and an application card. You can get the Gelli case in six colors and patterns. Price $19.99.
