> Someone else commented that you can de-register your number on Apple's site, but the person then said that it didn't work either.
I don't know how Beeper could possibly prevent Apple's iMessage deregister form[1] from not working. Apple handles whether or not you have an iMessage account, not Beeper. It might take a bit for it to fully be purged, but this was only announced/launched less than a day ago so I can't believe that person really waited before confirming it somehow doesn't work.
They complained that when they entered their number to de-register, they were presented with a "number not found" error. Which seems like a plausible error for a backdoor imessage implementation.
