Yeah I tried that one too. Deactivated my number on imessage on my phone and turned it off everywhere else I used it. People sending me texts still send as imessage rather than SMS and still show as delivered on the senders end. My new HTC never gets any of it. Even worse none of my existing imessage devices get the message either. It's simply gone. An Apple support rep actually suggested that I have everyone that I text with delete their conversation thread with me in their app in order to fix the issue. Seems like an unreasonable burden to put on the user. Needless to say attempting that on a few friends phones did not seem to work.
