iOS 4.1 build 8B117 (InternalUI)
|Build of iOS 4|
iOS 4.1 build 8B117 is an InternalUI build of iOS 4.1. Interestingly, along with the internal applications, SwitchBoard is present in this build. This build will look like a factory iOS build if SwitchBoard is started. Also, attempting to launch SwitchBoard by tapping its icon in SpringBoard will result in SwitchBoard crashing on launch.
