More and more information is appearing supporting the claim that the iPhone 5s has been delayed due to production issues.

KGI Securities analyst Ming-Chi Kuo claimed that issues with colour coatings for the fingerprint sensor said to be included on the iPhone 5S are likely to push back that device’s launch from a June/July timeframe to perhaps September or later.

A low cost iPhone is expected to launch as the same time as the iPhone 5s but will not include the finger print sensor but carry the same 4 inch display.
