To all my UBiQUiO 503G customers. Please note that when you open your box, you’ll have what seems to be two sync cables, one black, and one black with a yellow tip. Don’t worry, the one with the yellow tip is a radio upgrade cable and you do not need it just yet. Use the all black one as your sync cable and save the radio upgrade cable. It has been provided to you for future use. We’ll be issuing a 3G radio update to improve the performance of your device at some point in the future. There’s nothing wrong with it now, but improvements always become available and we want to make sure you are always up to date.
