lockdownd[26] <Error>: libMobileGestalt computeUniqueDeviceID: total time for bb to return imei: 0
I was getting this message when I was trying to deploy a Unity3D game to my iPad, after some research I discovered that what was causing this crash (just after the app was installed on my device, at the splash screen) was the Code Signing Identity in Xcode. In my case it was configured with a ADHOC distribution not with a iPhone Developer profile.
To solve this problem try to set your build setting to your iPhone Developer profile and you should be able to Run in your device without crashing 🙂
