Failures to register for push notifications

[crspybits]

The scenario looks like this:

1. I've been installing dev versions of Neebla to my iPhone, which give (expectedly) failures registering for PN's-- because they're connecting to the prod server, and this will try to use the wrong certificate.
   2)I install a production (app store) version of Neebla, and I get (unexpected) failures to register for PN's. This happens when the app launches and first goes to the Albums screen.
2. When I look at the logs in the server, I see a failure of authorization.

I think what's going on here is that:
a) the cached auth token has been evicted on the server
b) the auth token, on launch, is being refreshed
c) but there is a race condition on getting the new auth token (through Google's SDK in the iOS app) and landing on the Albums screen-- and the new auth token doesn't get sent to the server.

HOWEVER, when I kill the app and and retry, several times, I still get the problem with registering for PN's. Perhaps I didn't let the app sit long enough to get the new auth token?
