Hi Jean,
I have just noticed you have not applied for the beta program, and that's why you couldn't install it on your iPhone.
Apple restricts the distribution of iPhone applications so that every copy that is installed outside of the iTunes app-store must be registered at their provisioning portal. Since you haven't applied to the beta program, I did not ask them to register your device UUID, and that's why you were unable to install it on your iPhone.
Best regards,
Uri
