So I bought a few lightning cables last month before the 5s came out and they were working great with iOS 7 and seem to be still working fine with my iPhone 5 with the latest iOS 7 update. Problem I have is that they seem not to work with my 5s. I have them both sitting side by side and taking the cable from the 5 which is charging great with no warnings to the 5s and up pops the not compatible message and no charging. So my first question is: does the 5s actually have a different lightning dock that will pick up 3rd party lighting cables and not allow them to work? 2nd question: is there anywhere UK wise that have lightning cables that will work with the 5s at a reasonable price to pick up a few that have been tried to make sure they work? Now I know there is the argument that buying a phone at that price then whats £15 when it comes to charging it. But really there is no need for it to be that price and when you want a few (like I do) car, work and spare ect that £15 each time mounts up pretty quick and its always good to have a few handy. Thanks for any suggestions.
