i have an iphone 5 that is a little over 12 months old. a few weeks ago the lighting cable (that was supplied by apple with the phone) stopped charging the phone. i tried different wall adapters with the same result- no charge. also, when i plug it into the pc it is not recognized. so i used my dads lightning cable from his ipad air that is only 2 weeks old so the cable is apple and brand new. that too stopped working. so now my cable and my dad's (boy is he pissed) do not work at all. i've read about some issues with after market/generic cables but these are original from apple. what's going on?
