Finally, for anyone who owns or intends to buy an iPhone, the most vulnerable part of this device is its touch screen. As a result, there's a wide and growing array of useful accessories, including many protective cases. For me, many of these add-ons take away from the perfect size and weight of the device, though. As a compromise, to cut down on the possibility of scratches and abrasion, I highly recommend the Crystal Film Set, available from the Apple Store for about $15. This clear film is custom shaped for the face of the iPhone, complete with holes for the speaker and Home button. The film affixes to the screen by clinging with static electricity, and it really does stay on well. There are two sides to this film. The slightly tacky side should be the one to make direct contact with the iPhone's glass. It's a little difficult to apply because dust and air bubbles are a little hard to control. A couple of tips: A piece of Scotch tape will lift up the film once it is applied. Use another piece of tape on the tacky side to remove dust or small hairs. When you lay the film down, you'll have fewer air bubbles if you roll it down from one edge of the glass to the other. Use a fingernail or soft plastic straight edge to direct bubbles to the edge of the screen. Don't push too hard on the touch screen.
When properly affixed, you'll forget the Crystal Film is there. You really have to look close to notice it at all. And your screen has added protection, something you'll definitely want if you use your iPhone as much as I expect to use mine. To put it simply: Apple hit a home run with the iPhone.
