mobileGetDeviceToken doesn't work until after re-install?

[Mike Kerner]

This is weird.  I have an app that was running on a device, with APNS
enabled.  I asked it to return mobileGetDeviceToken, and it returned
empty.  I checked the push settings for the app, they were ok.  I tried
recompiling the app, no joy.

Finally I uninstalled the app and reinstalled the same version, and it
worked.
