Summary: The projector worked with OS4 on the iPhone but my phone has the newer operating system (OS5)and did not work with my phone. I am sending it back for a refund (no option was given to send it back for a replacement). Does that mean this is a known issue? I purchased another one from a different vendor but have not received it yet. I can't wait to try it when I get the replacement.
Only VGA connection works, HDMI and dock connection not.

Summary: I give it 2 star because so far VGA connection works great. No more than 2 star since VGA connection is the only way works well. I tried HDMI input on 3 computers (both MAC and PC) and 2 different HDMI cables. None of them works well, you can see the picture and can set resolution to 1080, HOWEVER, the picture is very unclear. I have to use VGA connection and 720 resolution, which give much better picture quality.
