The Incase slider iPhone case is a classic by now and has spawn many imitations. Slider cases offer great protection for your iPhone but at the cost of being a bit bulkier than most. If you are prone to dropping your phone, then this is a reasonable choice to make. When buying sliding cases, I would recommend buying from name brands like Incase as these must be precisely made. I have tried no brand sliding cases and they are either too tight, making taking it on & off difficult or too loose. Although, too tight is my typical experience. Another common problem with slider cases is that it will tend to pull off the screen protector when sliding in the phone. This is made worse if the case is made too tight. I don’t have this problem though as I no longer use a screen protector; figuring that the tough gorilla glass is protection enough. Some people may insist on one for privacy reason or to reduce glare. If so, a sliding case may not be the best solution for you. The Incase iPhone 4 Slider Case – Soft Touch (AT&T & Verizon) (Black) is available from Amazon.
