iHome iP40 and iphone 4 issues

[rakidder]

I got an ihome ip40 for christmas and it has been working fine with my iphone 4 until recently. It still charges the phone, but when I try to use the ipod function on the dock and play music, it says "accessory is not compatible with iphone". Any suggestions on what the issue on this may be? Thanks

I tried cleaning out the pins on the bottom of the phone, but still no luck. Still comes up with a message saying "This accessory is not supported by iphone" when I try and play it through the speakers.
