Iphone 3,3gs,4 and 4s ringer problem fixed
Small hole by the headphone jack clean it with needle meaning put the needle in the hole and take it out and your phone will be perfect simple .
I wanted to share one more thing i went to apple store today and they said i am 14th month now so they cant replace it only they will replcae if i pay £139 so i refuse to pay that amount and came home and try to do everything but at the end succeeded by doing this .
