I bought this cable from an Apple store. Got it home, connected it to my iPad and my iPhone 4S to find that I was getting sound but no image. Went back to the store and queried the product thinking that it must have just been a faulty example.
In the Apple store they tested it out and agreed that it did not work. They were about to replace it but I asked them to test out the new replacement one too - just in case..... It did not work either. And then another 2 cables were also found to function incorrectly too.... Red-faced, they told me it must have been a faulty batch!!!!
