I have a iPhone5 (black) 64gb ATT running iOS 6.0.1. Its speakerphone makes no sound when: - Making phone calls - Receiving phone calls (phone doesn't ring) - Playing music via Music - Playing music via Pandora - Playing music via Songza - Playing YouTube videos - Trying to play a translation using Vocre or Google Translate This started before I left on a 4 country, 16 day trip ~ 3 weeks ago. As you can imagine, it was a huge pain to have my phone like this while on the road. My bluetooth headphones still worked for listening to music. My wired headphones work also. I have tried: 1) Turning Bluetooth on and off 2) Logging out of iTunes and rebooting 3) Pressed the Home and the Sleep-Wake button until the phone shut down and re-started. 4) Toggling the Mute key on upper left side on and off based on other suggestions topics: https://discussions.apple.com/thread/4337519?start=45&tstart=0 https://discussions.apple.com/message/19827763#19827763 http://forums.macrumors.com/showthread.php?t=1506506 Water damage is not a possible cause. I have not yet upgraded to 6.0.2. Is there a particular way that I should approach the installation to 6.0.2 to have the best chance of fixing my speakerphone problem? I am syncing to iTunes on a Windows XP laptop.
