    Basically everytime I try to make a call my blackberry makes a very high pitched noise like ridiculously high pitched its barely audible and then it freezes the phone and restarts it.

    Blackberry 9700
    v6.0.0.448
    platform: 6.6.0.124
    Network: Wind

    Does anyone know a fix for this problem.

    Cheers

    I would reinstall OS.

    .461 works great. i used BB Boss to shrink it too.

    Have you tried a battery pull? Are you using a wired headset? Have you tried a warranty repair or exchange through wind?

    i had the exact problem after replacing the LCD screen.

    had the problem for about 15 mins and i couldn't figure it out

    so i lightly smacked the top left corner, out of frustration and the squeal stopped

    So i'm assuming a loose cable may be the cause?

    Also i noticed when u switch to speakerphone, there is no squeal.

    just a wild guess.
