I bought a pack of 5 third party lightning cables from china about 6 months ago. They have always worked on my iphone 5 (6.1.2). Now that I got my iphone 5s and the wife has the old iphone 5 (both on 7.0.2) these cables are dying one by one. When I first plug them in you get the "this cable is not supported" but the cables still charge and sync for a day or so. Now they they are dying one by one in the last 72 hours. You get the 'not supported" message but no charge. I can't believe they are just going bad all at once and it's weird that they work for a day or so after 7.0.2. was installed. Is apple reading some 'id' off of these cables and blocking them? something else? Do third party lightning cables even work any more with ios 7+?
