ios - TestFlight fails to install app and cannot delete partially installed app

Question

I have an iOS app I am deploying via TestFlight. The app installs fine on an iPad 1 running iOS 5.1.1. The app will not install on my iPhone 4 running iOS 6.0. Both devices are included in the provisioning file. The app runs fine in the 5.1 and 6.0 simulator.

When I try to install the app to my iPhone 4, I get the following screen:

In addition, I cannot delete the partially downloaded app (it's there in the lower right hand portion of the home screen). I've tried restarting the device and resetting the device without success.

Here is the console output I get from the phone when I hit Retry (stuff in <<>> is redacted):

Update

The app installs fine on another iPhone 4 running iOS 6.

Answer 1

I took my phone into the Apple store today -- and, shockingly, they were able to delete the app. All they did was pound on the delete "x" about 50 times and it eventually went away.

After getting the corrupted (?) app deleted, TestFlight can now install the app without a problem.

No idea....
