ITunes Modes

iTunes seems to have different "modes" hidden inside of it. None of them are useful for unlocking, jailbreaking, etc. This is more of a fun article, just because we are tinkering around with something that we should not be. Please note that:
 * You will need to restart iTunes after changing these settings.
 * You can download a GUI for doing these actions on Windows over here.
 * This is an initial study compiled by chronic.

Turning them off
In any of the parts of this article that show a command used to turn on an iTunes mode via terminal, then to turn them off, all you have to do is replace YES in that command with NO (1 with 0 for Windows).

Store Activation Mode
This mode is flipped on for the iTunes versions installed in Apple Stores computers and official carrier stores. It is used to activate iPhones (iPhone 3G and newer) and iPads (Wi-Fi + 3G models). If you enable this mode and connect an activated device you'll get a warning and the device will be automatically ejected.

Mac: defaults write com.apple.iTunes StoreActivationMode -bool YES Win: "%ProgramFiles%\iTunes\iTunes.exe" /setPrefInt StoreActivationMode 1

Store Genius Mode
This is probably used at the Genius Bar in Apple Stores. If you enable this mode and connect an activated device you'll see the " Welcome to iPhone/iPad/iPod touch " screen. Clicking on " Continue " ejects the device. Mac: defaults write com.apple.iTunes StoreGeniusMode -bool YES Win: "%ProgramFiles%\iTunes\iTunes.exe" /setPrefInt StoreGeniusMode 1

Store Demo Mode
This is probably used on demo Macs in Apple Stores. It just prevents a device from being backed up. Mac: defaults write com.apple.iTunes iTunesStoreDemoMode -bool YES Win: "%ProgramFiles%\iTunes\iTunes.exe" /setPrefInt iTunesStoreDemoMode 1

Device Backups Disabled
This seems to be the same as. Mac: defaults write com.apple.iTunes DeviceBackupsDisabled -bool YES Win: "%ProgramFiles%\iTunes\iTunes.exe" /setPrefInt DeviceBackupsDisabled 1

Nike Kiosk Mode
Syncing is not allowed under this mode. Judging by the name, it's probably meant for Nike stores (to pitch Nike+). Mac: defaults write com.apple.iTunes NikeKioskMode -bool YES Win: "%ProgramFiles%\iTunes\iTunes.exe" /setPrefInt NikeKioskMode 1

Carrier Test Mode
In this mode, old versions of iTunes used to allow you to select iTunes Carrier files when you Shift / Option clicked. This allowed to restore Carrier Settings (.ipcc files) from any carrier providing they are signed by Apple (on a non-jailbroken iPhone). With newer versions of iTunes, you can do this without having to enable. Mac: defaults write com.apple.iTunes carrier-testing -bool YES Win: "%ProgramFiles%\iTunes\iTunes.exe" /setPrefInt carrier-testing 1
