My iphone 4 had been out of commision for a month or so because the screws that hold the back were gone (it was previously my stepmoms) and it fell and hit the ground ripping the battery out. I ordered one and put it in. When I push the home button it shows the icon for asking you to pluh in a charger when I do it goes to just the empty battery and doesn't charge. Its like it recognizes the charger but doesn't charge it. I've tried cleaning the connector port of dust but that hasn't changed it. I was hoping someone may help. I was thinking I might have to replace the connector port. Any help would be apprieciated.
