I had to write about this. This may piss off some iPhone case makers. Apple’s newly-announced iPhone 4 is using the same scratch-resistant tempered glass on the back as it is on the front.
Any iPod or iPhone owner could tell you that the polished backs of all of these devices have had a difficult time with tiny scratches. These devices always look so shiny and beautiful when they come out of the box for the first time, but then they are tarnished by life in the real world, (just like people).
I do not think this blog post exists for any reason beyond my excitement that I may own an iPhone 4 (or possibly iPhone 5) and that it will not need a case the way my 3GS does now.
