My nephew poked a pin through the rear speaker grill of my brother's AT&T Moto X and totally killed the external audio. I'm looking to help him replace the headphone jack/speaker assembly, but the cheapest devices I can find on ebay (won't charge, cracked screen, bad ESN) from which I would rob this assembly are all going for well over $100.
I'm also having a heck of a time finding a spot for such replacement parts so I'm guessing they don't exist just yet. Anyone have any clues to track down such an assembly, or have a busted X you're looking to part out? :P
