Hi!...

But the problem is when I'm making or receiving a phone call, I can't hear and they can't hear me. speaker, mic, everything is working fine in apps, iTunes... record normal video, music and video playback with normal audio, using headphones, speaker or Bluetooth is ok in apps and iTunes... the problem is only with phone calls, phone audio is not working... incoming call phone rings perfect, outgoing call going well until the call is answered, no audio during phone calls, sending sms, Internet, wifi, everything is ok but there is not audio during calls... Please any advice? some help please!!... Already reset all content and settings, latest version of iOS 4.3.3, phone is restored but the problem remains!!!... H
