Oke.
So i've istalled a new version of Itunes.
Now when i but the USB cable in my computer and then in my iPhone 3G
I hear 2 times the sound when you connect something to your computer.
My iphone doesn't connect then to my pc. It even don't charge battery
My other USB hardware works in the port.. But why not my iPhone 3G ! 
Any help here from the others? Maybe some of you guys have this problem to? so how to solve this thingy ?
Thanks! Mvkoe
