What I was wanting is the opposite, I want iTunes to OPEN when i plug in my phone, not the other way around. Right now, when i plug in my phone, it doesnt open itunes, but i want it to open and sync right away without me having to open itunes.
Notice that I said UNcheck that option... Also, in the "Summary" pane for your iPhone in iTunes be sure "Automatically sync when this iPhone is connected", is checked. (This won't work if the "Disable..." option in the iTunes prefs is checked.)
