I've got a 3GS iPhone, I've downloaded the PDF and files to update the carrier settings to Telecom XT.
I've read the instructions over and over.
I've applied the patch to my iTunes 8.2 on my mac.
When I hold down OPTION and click on UPDATE, it allows me to browse to the folder, but the IPCC file is greyed out!!
It won't allow me to select it.
What am I doing wrong?
Does that mean that the patch hasn't been applied successfully or is it something else?
