I have not much to complain about in relation to this cable quality finish (maybe just the USB portion of it is a bit small, and does not recharge the iPhone if unfortunately the USB port n 'is not the same side as the component jacks on your TV, which is the case on certain model SAMSUMG). I takes only three stars because after, it was the iPhone applications (in my case a 3GS) that are lacking. Some applications have in the past supported the TV-Out mode, but after update, this mode is sometimes removed because unfortunately little used, in the case of GPlayer applications and CineXPlayer. Only the iPhone's photo application manages to correctly use this cable and the video official iPhone application One last thing, the picture quality is quite average of 640 * 480 for NTSC or 768 * 576 for PAL. Image will be clearer with a Composite AV cable (5 records, 3 for color, and 2 for the sound). Or even better, HDMI (available from the iPhone 4), but again, it's the application that may be lacking.
