Every once and a while my friends and I aren't receiving messages through Blackberry Messenger. The "D" will show on the person sending the message, but it will never get to the recipient. I'm unable to receive messages now and I've done 2 battery pulls but it hasn't helped. Anyone else experience this ever? and does anyone have a way to resolve the problem?

try deleting all your service books then batt pull, then once on again, go options, host routing, menu, register now, then go to tmos BIS site and resend all your service books, see if that fixes it
