RONNIE, if it does not charge, and obviously it works in the other phone, it is possible that you have a bad dock connector. That is the part that distributes the signals from the cable. I would start by replacing that one first. Here is the guide for it, and the part is available right here as well as many other places. There are of course a few other possibilities, like bad connection to the battery contacts and burned out components, but start with the dock connector first, after that reevaluate and let us know. Hope this helps, good luck.
