This accessory is not made to work the iPhone: Universal dock message.

[aaquib]

I have an Apple Universal dock and always get this message with an iPhone. It works fine on ALL my iPods(including the touch). I even have the iPhone 3G dock adapter(not that it makes a difference, just fits better), but nothing seems to work. What could be wrong?

Others have had a similar issue as well.

I get that mesage and all it's saying is you may get some gsm interference if you plug speakers into it. Mine syncs up and charges the phone fine so I just ignore it.
