It is also rumoured to be introducing a new budget iPhone, believed to be called the iPhone 5c. Analysts have said that Apple needs to launch a cheaper phone in order to help it recapture some of the mid-market which has been won by rival Samsung.
Reports suggest that the iPhone 5c will be an iPhone 5, with redesigned components to take advantage of smaller and cheaper components, alongside a less expensive casing.
It is likely the iPhone 5 will not be sold alongside the iPhone 5s and 5c, as the iPhone 4s was with the iPhone 5.
According to rumours, the iPhone 5s will come in three different colours, white, black and a new gold-tone. It will also feature a new finger print reading biometric scanner and be available in a new, larger 128GB size.
The iPhone 5c on the other hand is rumoured to come in a variety of colours, including black, white, yellow, red, green and blue.
