Beeper mini users who used their hardware to register their app with Apple's iMessage network may find their Mac blocked from the service instead, in what could be retaliation against the use of the controversial messaging app.

Beeper is said to be focusing on adding other chat networks to their “Mini” app, and preparing for a relaunch.
