I have just bought a 4-in-1 adapter for my G1. it SAYS htc on it and the thing says OEM (bought on ebay) and right out of the package, the 3.5mm headphone jack, the 2.5 mm headphone adapter, and the micro usb headphone thing did not work. i tried multiple types of headphones, skullcandy, apple earbuds, home phone mic, different mic, and htc headphones, none of which worked. but the charger did work. so i have no music, but another charger (thats 3 now) . the music stops when i plug headphones in (like it usually does) but then it would just continue to play through the back speaker. no clue whats wrong, anyone else share this problem?
