I, like most users here, have installed the "Offical" AT&T WM6 Rom from this site. I have noticed that when the screen is on, it makes a high pitch noise. It only comes on when the screen is on. Does not matter if the backlight is on or not. I (mistakenly) took my phone to an AT&T store to inquire about the problem and the tech told me that he could not do anything cause of WM6. I would need to downgrade to WM5 and see if the problem was still there. So...I am downgrading right now.
My reason for this post is
1.) Does anyone else have this problem with WM6?
2.) Does someone with WM5 have this problem?
The tech was saying that the driver for the screen was wrong and "overclocked", and that is why the screen was having noise issues. How much smoke was this guy blowing my way.
