We must take these photos with a grain of salt considering the large number of iPhone knock-offs produced in China each year. However, this particular source correctly leaked the spare parts for the Apple iPhone 5 before, which means that they do have a positive track record.
The next iteration of the Apple iPhone is expected to be introduced late in the third quarter of this year. We expect to see a higher capacity battery, an improvement in the camera sensor and the next-generation A7 processor under the hood. There has also been talk of a fingerprint sensor being included on the Apple iPhone 5S.
