Internal UI

The CoreOS section of Internal Settings on 8B117

The homescreen of two devices booted to builds of iOS 7 Internal UI. On the left is an iPhone 5 running 11A465 and on the right is an iPad 2 running 11B554a

Internal UI is very similar to production builds of iOS, but with some key differences:

• Internal UI may have a different build number from the iOS version it is based on, but not always.
• Internal UI has a large amount of added applications for debugging.
• Internal UI contains extra preferences, such as Internal Settings and Carrier Settings.
• Internal UI uses debug or development bootloaders, similar to NonUI
