um i come back from eating dinner and my ipod touch has been plugged into my computer and i move the mouse to stop the screen saver and i have a message saying my device could not sync with sync services or something. then behind it. it says "There is no SIM card installed in the iPhone you are attempting to activate. please disconnect and insert a SIM card in your iphone." THE WEIRD THING IS....my device is a ipod touch 2G on 3.0, any body else have this wierd thing happen.
