I can't send messages via BBM. When I send a message, I get a checkmark next to the message, but never see a D or R. I've received incoming messages and my responses to those messages are received, but if I originate a message, it doesn't seem to go through. I've re-registered the host routing tables, re-sent the service books and done numerous reboots/battery pulls and nothing has worked so far. Any suggestions would be greatly appreciated.
