    Find the old carrier file and do the same thing, or, just restore.

    Its hard to get the old file, but there is another way:

    1. Rename it from .ipcc to .zip
    2. Unzip and open the folder Payload
    3. Right click/control click on the .bundle file and hit show package contents.
    4. You will find a file called Info.plist, open it in Property List Editor.
    5. Under the version it should say 5.1, change that to 3.0
    6. Save the file, zip up the Payloads folder, and rename it to ATT_US.ipcc
    7. Option-click restore in iTunes and select that file.
    8. This will replace the 5.1 version, but the phone will still have the 5.0 version that came on it

    Note: It is important that you click restore not update, otherwise it wont install and older version
