there are two mics on the iphones. one on top and one down where the speakers are on the bottom. it could be that theyre clogged up

Its possibly the battery you got was defective or the screen is not working. Have you tried to plug it in after you installed the new battery? If so what does it display on the screen?

i would go get a big plastic bin juuust big enough to hold the keyboard and about two big bottles of 91% rubbing alcohol from walmart and take apart the keyboard as much as possible and submerge it in the rubbing alcohol and shake it around in there to loosen up any debris and corrosion that may have occurred from the liquid then let it dry for like an hour and try it. then if still nothing repeat

and u cant jailbreak third gen. at least not without having to plug it in everytime u turn it on
