that is the file i used, it didnt work, i've tried probably every single ATT_US.ipcc file out there and none of them have yielded any different results. on top of that my iphone is running 3.0 but the xcode log keeps complaining that the ipcc files fail verification, but afaik they didnt start signing the ipcc's till 3.0.1 or 3.1, so it's strange. i've had to install the bundles into /var/mobile/Library/Carrier Bundles on my own to try new ones.
