I just upgraded my iphone from 1.1.4 to 2.0.1 using WINPWN and when i disconnect my iphone from my computer the volume turns all the way down by itself and it will not allow me to turn it back up. I can only control the volume when I plug my fon back into my computer.

Can anyone help me please is this a bug or something?

Also sorry if I am in the wrong forum i am new.
