Ok, while doing a simple LCD repair on a 3G i dropped and got the white screen of death, i pulled with a little too much gusto on my suction cup and pulled the screen, tearing the ribbon cable that connects the mic/dock board. GREAT. so i order a replacement and install it, piece of cake. however, the mic doesnt work... dock works fine, speaker works, what gives? did software restore, no prevail. tried the headphone jack plug-in and removal, no dice.

could it be possible that my motherboard took a dump when i did this? what is that cushiony grey stuff that separates the boards? does it work as a grounding surface?

about to throw this thing! help!
