Rumours have been going round recently that there will be a new iPhone which is supposedly going to be released this Autumn (Fall). The iPhone 5 is supposed of have the 4G LTE support that the new iPad has, and some ports have been moved around and made smaller so better components can be added in. (not specified.) The screen is also bigger, due to the home button being resized down by half, and there is also rumours that there is actually a complete re-design.
