I have always used Power supports Crystal Film since the first iPhone was released due to its perfect fit, easy application, great protection and lost lasting protection. I have seen many other brand like the few I said in the title that seem to be at the top of the iPhone protection pack. I am looking for that same Crystal look with full protection and something that will cover both front and back of my new iPhone 4. What are the pro and cons of these makers? What do you use and why? And what will you be getting for you new I4? Thanks for all your feedback on everything you know about every company and their products!
