After upgrading my iPhone 5 to iOS 7 beta, it seems I have to re-connect it to Testflight. Unfortunately, I can't install the provisioning profile:

After selecting 'Reconnect Device', 'Install Profile', 'Install Now', the alert is 'Profile Installation Failed. You iPhone is not activated'

I tried to remove the previous profiles, clear Safari cache and reboot, but no success...
