[Advice] Different iPhone headphone jack part no. ?
I found out that Apple is assembling a new headphone jack flex cable w/ buttons. There are 2 different part numbers. The older one is part no. 821-0449-09 and the newer one is no. 821-0600-A. They are NOT compatible! If i assemble an older cable in a newer iPhone, the iPhone get no sound from speaker. After inserting the headphones, no sound from the headphones but sound from speaker.
did anyone get this problem? And anyone knows the difference?
