Reconnecting the data cable is actually pretty easy. Just hold your screen at a 90 degree angle and put it on your underlying surface (and not on the back part of your ipod). Then just use the opening tool to reconnect the cable. The cable is long enough. If you connected it properly try pushing the home button on the back part (not the actual button). If done properly, your screen should light up. (if not try again to connect the cable) Then just fold the screen onto the back part without lifting it. The cable disconnects very easily.
