As many people already know, the new iPhone's back plate is easily user removed (just two simple screws and you slide the back off). What if a company started to produce new backs for the iPhones. Not just the glass but I am talking about rubberized backs or stainless steel backs or maybe even bamboo backs. Not only would just eliminate the possibility of the glass breaking, it would provide a level of customization iPhone users really haven't gotten. You would not have to worry about antenna issues(besides the ones now) because it is now placed on the side. Maybe this is not possible but I don't see why not as long as it is machined well. Personally, a brushed aluminum back would look extremely classy while adding some functionality. Just a thought.
