The iPhone 5S comes in silver, gold or 'Space Grey' and will cost £549 for a 16GB model, £629 for a 32GB model and £709 for a 64GB model.
Innovations include an A7 chip, making it the "world’s first smartphone with 64-bit desktop-class architecture for blazing fast performance"; a thin and light design; a new 8-megapixel iSight camera; and Touch ID, that allows users to unlock their phone with one touch of the home button, using fingerprint recognition technology.

Not only in terms of keeping new features under wraps, but also continually delivering a star-studded list of innovations with each launch."
