As the WWDC 2012 is just around the corner, many people start to discuss the long wait iPhone 5. Previously, we heard a rumor which claims that iPhone 5 will support HD FaceTime (yes, this is possible). Today, we would like to bring another great new rumor from 9to5Mac which claims they have a iPhone 5 back cover. Check the photo above, it clearly show that iPhone 5 will have a edge to edge bigger screen. However, this is just a rumor. Please wait and see.
