I bought the phone through independent delear so i got it for cheap price but after a week without calls also there was a high pitch sound coming from speaker.I called cingular and they sent me a silver one instead of black.Even in those phones there was a sound.To observe the sound just flip open the phone and hold it as if you are talking. I tried 4 phones and felt noise in all the phones.The one I bought had noise level quite high and was problem with talking on phone.
