I love the iPhone 4's design, with one exception. I am on record that the glass back is a design flaw that I would like to see go away and it appears that the iPhone 5 may indeed remedy that with a return to aluminum, the favorite material of Apple's recently knighted Sir Jony Ive. Indeed, the glass back is the primary reason I keep my iPhone 4 in a case, where it would harm the aesthetic appeal, per the late Steve Jobs. Fortunately, there are some good-looking cases, including a few with aluminum components. I've shied away from them because they often require special tools to insert or remove the iPhone from the case. Considering that some docks do not accommodate those cases, it can be a pain to carry a special wrench just to remove the case to dock the phone.
