My iPhone keeps connecting and un-connecting why trying to sync?

[Medeiros2227]

Why I try to sync my iPhone, it will connect and un-connect repeatedly? Any suggestions?

Do you have it plugged into a USB hub? Try connecting it straight to the computer instead of using a hub.

Same problem here... fixed

Take your cable to Apple store and exchange. Mine fixed after that.

I get the same thing and iTunes won't start when I connect to the front USB hub. I get a phantom Dadunk without my iPhone being plugged in at all. Weird.

Check your drivers... also try starting iTunes manually. I think there is a setting that allows you to connect without bringing up iTunes which is probably what is happening if you hear the dading.
