When it comes to the shape of the iPhone 5, while it is set to be larger in general than previous iPhones, but is still set to be a rectangle, rather than the teardrop form that many rumors had led consumers to expect. However in addition to the bigger 4 inch display expected (compared with 3.5 inches on previous iPhones), which will enable Apple to compete with phones produced by rivals such as Samsung in providing users with an experience which is more immersive, the iPhone 5 is set to offer a range of improved features including a better level of display resolution thanks to better density of pixels. This should make the experience of watching films more enjoyable and also improve the quality of photographs and films produced using the phone itself.
It is also widely believed that Apple plans to incorporate the LTE high speed network that was included as part of the most recent iPad. This was the first iDevice produced by Apple to have this feature and, given that the company originally wished it to be incorporated into the iPhone 4S before accepting that it would have meant too many compromises with the basic design of the phone, it seems virtually certain that they will wish the iPhone 5 to have this feature.
