    You are missing the [ ” ] on the command posted
    if you entered as you gave it to us [Thank you by the way] it does not work for me on a Windows 7 32 bit machine [C:\Program Files\iTunes\iTunes.exe” /setPrefInt carrier-testing 1]……

    So I Added the missing [ ” ] to get this [“C:\Program Files\iTunes\iTunes.exe” /setPrefInt carrier-testing 1] and now I was able to select .IPCC files to load to the Iphone 3gs [ using Itunes 9.0.1 ]

    Thank you….
