IPCC Files

The following summary is made from an article from osXDaily .

iTunes carrier testing mode allows you to manually load signed .ipcc carrier files onto an iPhone or cellular iPad, these .ipcc files contain various carrier settings pertaining to voice mail, MMS and SMS, Personal Hotspot, APN settings, and other network-specific preferences. If you’ve used an iPhone on T-Mobile or even as a prepaid phone you may have experience with these files, but other than making network configuration easy they can also be used to forcibly enable features that are otherwise disabled by default, like Personal Hotspot on certain international iPad 4G devices. We’ll cover how to enable carrier testing mode, how to find ipcc files, and then how to use those IPCC files with either an iPhone or iPad with a cellular connection.

For Mac OS X:

• Quit out of iTunes
• Launch Terminal from /Applications/Utilities/
• Enter the following command at the prompt and then hit return:

 defaults write com.apple.iTunes carrier-testing -bool YES

• Relaunch iTunes

Finding & Downloading .ipcc Files All signed ipcc carrier settings files are stored in an xml file on apple.com, you can not access that gigantic list anymore from http://iphonediags.apple.com/version.xml.
