John Gruber on Beeper’s Last Hoorah
What I had been seeing during the week before Christmas is that Beeper Mini half-worked: messages from Beeper Mini on Android would go through to Messages on an Apple device, but from any Apple device, you could get one message through to an Android device running Beeper, but only one. After that, messages sent from an iMessage user on an Apple device to a user running Beeper Mini would silently fail.
