Remanufactured 44059109 Yellow Toner (8000 Yield)

The new iPhone 5S is a solid upgrade of theiPhone 5 , but with a few key changes: the processor is more advanced than ever, the camera has been upgraded and, most importantly, there's a fingerprint sensor.

On top of that there's the added bonus of a faster GPU (to help power all those teeny tiny pixels rolling around and changing colour in the display) as well as an uprated power pack to keep things moving.
