Mockup design of iPhone 5 with Aluminum backing
GadgetsDNA points to a Mac Otakara report about the upcoming iPhone 5. According to a Chinese source, Apple will be abandoning the glass backing of the iPhone 4 and moving back to an aluminum casing. Apple's first iPhone also shipped with an aluminum back casing. From the translation:
Decision to design similar to iPod touch instead of using glass is supposed that Apple seems to stop problems which are told widely damages from scratching, difficulties of painting white and weight of glass.The antenna will also be redesigned which means Apple will also be abandoning the current external iPhone 4 antenna design. The iPhone 4 antenna was the source of a major controversy over signal loss and attenuation when it was held in a certain way. The iPhone 5 is also said to have the new Apple A5 processor and will likely be announced in June/July.
