Won't recognize charging cable.
My iPhone 4 recently stopped recognizing the charging cable. I have tried this on the wall charger and through my computer and still nothing. It won't turn on at all because the battery is fully dead but if you hold home and the power button it will flash the charging sign. I don't know if this is a battery issue or a charging assembly problem or a bad dock connector. I am fully prepared to buy the parts necessary but would just like to figure it what is exactly needed. Ay help would be great.
