I've had my Touch for months and had it jailbroken at 1.1.2 for a while - all with no problems. For Christmas I got an Apple Universal Dock. On Christmas day I was using this just fine. I could dock it, sync in dock, use remote etc no problems. Today, Boxing Day I put the Touch in the dock and iTunes doesn't list it under devices! Everything else about docked use is fine - it plays through line out, the remote works and the iPod is charging. If I connect directly to the USB cable, iTunes recognises it just fine. If I connect my wife's new Nano to the dock, iTunes recognises that just fine. So it's not the Touch dock connector (works fine on cable), not the Dock connector (works fine with Nano) and - in theory - not the Touch software as it works fine on cable. I've tried searching the forums but this is an inherently tricky search to do (too many generic terms). BTW, iTunes is possibly seeing something when I put the Touch in the Dock because if I try to quit iTunes after putting it in the Dock, iTunes hangs. I have latest iTunes running on latest Leopard. Any ideas?
