Historically, Apple has offered its older models as a low cost option for those wanting a bit more value for money, but in recent weeks there are been increased speculation that a new value smartphone would make an appearance. There are also rumours that a low cost iPhone could sport a range of different colours other than the traditional black and white found on most iPhones.

As for the prospective iPhone 5S, this is rumoured to include a fingerprint sensor for added security. This is likely to be mounted on the home button of the devices. Apple acquired fingerprint security firm AuthenTec last year, and the initial beta of iOS 7 contained sensor settings.

In June, Apple debuted its new mobile operating system; iOS7 and this should land on most people’s iPhones, iPods and iPad this autumn.
