I earn apple’s 32 gb iPhone 4s with Rogers. The apple’s with no doubt has a good sound, so most of the people earn it. But since I am using the Apple hands free headset with the phone during a call, an echo sound is been observed. It does not occur when I play in speaker mode. i tried using other hands free but the same problem. I tried rebooting, in advantage also restored phone back to factory settings as a latest phone and still no resolution.
