When people talk about the supposed design of the next IPhone, and refer to the possible curved back that we've seen mock-ups of on various sites, people often say a curved back would be going backwards to the previous iPhone designs. Why isn't anyone comparing a new curved back design to the current gen iPad design. A design similar to iPad 2 would make sense. Using an aluminum body instead of the stainless one would eliminate the scratching issues that plagued the previous iPhones and the iPod touches.
