ok, i'll try to make this as short as possible.... iphone 4, all of a sudden about 2 months ago when i would make a phone call, the "speaker" button will automatically illuminate soon as the call starts...yet no sound comes thru the speaker at all, wether i toggle the speaker on/off, doesnt matter... the call connects...i can't hear, and the person on the other end can not hear me... took phone to "genius" bar, and the guy told me it seems like an internal hardware problem... im 2 months out of my warranty so apple wont help me or give me a replacement... i just want to know what "hardware" in the phone can/is causing this problem...if need by i'll take the phone apart and fix/replace the part....i just have no clue what it would be... this happens on 98% of ALL calls on this phone!!! SOMEONE HELP ME PLEASE!!!!! thank you... ---------- forgot to mention....i also tried doing a restore...no luck... tried using a bluetooth...no luck... but sound comes out during music play etc.... HELP!!!!!
