    Does anybody else have this problem, or is this specific to my phone? Whenever I make a voice call, there's a highpitched hum in the background, it's pretty loud. It seems to be linked with the backlight, and gets a little bit quieter if I turn down the backlight. By comparison, my treo 300 has no hum. It appears to be coming from the LCD, because even before a call is made it's pretty loud.

    Anyone else find this incredibly annoying? Or is this just my phone?
