In 10.5, every time I put my iPhone in my dock iTunes pops up. Any way to disable this?
When you put your iPod in, let iTunes open.
Under the Devices tab on the left, click on your iPod. In the main window it should open up some details and options for your iPod.
You want to be under the 'Summary' tab, which is the one it should open up to.
Mid bottom are three boxes. Just uncheck "Open iTunes when this iPod is connected" and it won't do it anymore!
Edit:
Here's a pic just in case you need it.
