Hi all, thanks for reading this. I recently put my Iphone in to have the power button replaced. When I got my iphone back the GPS function was not working on it. The mute button stopped working as well so I put that in to have it replaced as it was replaced along with the power button. My question is what is the probability of the repair messing up my Gps. I know the Gps was working before they opened it up as I used it to find their repair shop. Although I have never accused them of breaking it they seem to already becoming up with excuses like I dont know how it stopped working as the engineers went no where near the Gps etc. Also no firmware or baseband changes were made during the repair. Any info would be greatly appreciated.
