Falcon Pro Google + page has details on its new beta app.

Why the beta? Developer Joaquim Verges has announced that Falcon absolutely has run out of user twitter tokens, the app itself is not dead. If you still have a token through Falcon Pro, you’ll be able to use version 2.0.4 of Falcon Pro.

However, if you don’t have a token, that is you have never signed in using the app to twitter, there is a back door. Full details are on the Google Plus page.

Somehow I see this ending in tears, with twitter totally banning Falcon Pro from using its services.
