ONLY ORIGINAL APPLE CABLES WORK WITH NEW APPLE DEVICES (iPhone 5 range, etc).
With every "compatible" cable I bought from Amazon and eBay, my iPhone 5S just says "This cable is not certified and may not function correctly with this device" - and of course it DOES NOT WORK - you can't even charge the phone with a non-APPLE cable.
After buying countless "iOS7 compatible" USB-Lightning cables, the ONLY cable that has actually worked so far (apart from the one that came with my iPhone 5S) is the one I've just paid £15 for at the Apple Store. It may be CRIMINAL, but that's how Apple works these days. Lock out the competition by embedding a small sensor in each cable.
As far as I can tell, NONE of the ones on Amazon actually work with iPhone 5/5S even though they SAY it does. Read the reviews BEFORE BUYING.
