*Help* iPhone speakers distortion
My iPhone 3G has always been working wonderfully until a few days ago...I often use speakerphone during calls, but now suddenly when I switch speakerphone on, there is a loud distortion and the caller´s voice is breaking up, making calls impossible. The speaker works perfectly when using iPod and I can make calls successfully without the speakerphone and also with headphones. Is this a software or hardware problem? Anyone had the same issue?
