If the lens cover is no longer sapphire crystal lens cover like in the 5G, so then what does it use instead? Anyone know? Does this mean that with normal use it will get scratches on the lens (cover)? My 5G is what, like 2-3 years old? And although it has tiny scratches on the display, there are non on the lens. The only thing that's really keeping me from upgrading is the lens cover... Which is why I ask. Do all other current Apple devices like the iPad still use sapphire crystal? Is it only the iPod Touch 6G which got left out?
