to sync or not to sync...

So I am still getting used to my new iphone 3G, and there's something I'd rather it didn't do, but I can't seem to get it to stop. It starts up iPhoto every time I plug it into my computer, even though I tried to tell it not to do that.

I unchecked the sync in the photo tab in iTunes, and was promptly informed that the photo sync would no longer happen, and I clicked "apply" and thought that was over with, but no.

It still starts up iPhoto every time, and I don't want it to do that. Maybe it's not doing the sync, but if not what reason is there for it to start up iPhoto? I'd rather it didn't do that.

Is there a way to stop it from doing that?
