The cable was supplied in good time (under 5 days), there were no instructions or other documentation - but there should not need to be. However as soon as I pluged it to my iPhone I got a message informing me that "This accessory is no supported by iPhone". The only option is to dismiss this, but no matter what I try to do I cannot get an image on my TV. I have tried differnt TVs, and differnt stages of the iPhone - turned off then connect cable, turned on with my home video running, with other videos running, with other applications & without any applications running. Nothing. I wish I had the reviews from others before wasting my time!
My iPhone is a 3GS which is not jailbroken so if you have a jailbroken one it might be worth the try, but do not get your hopes up!
