D means it was delivered, the D only appears when sending texts to the same network. A check means that it was sent, but a D wont appear if you send a text to someone on AT&T, etc.
Is this in your BB messaging or your SMS texts? I know that on Messenger, the check with the 'D' means your message has been delivered, then changes to an 'R' when they actually read it. On my SMS, it shows a 'D' when my text is delivered, but only if they are on the same carrier network (no 'R', though). Hope that helps!

actually the didn't work for me, i have the curve 8320, and I've been texting a friend and most of her messages have the D over the check mark, but not all, and then for my other friends that have sprint, and cingular, it ranges from like either 7 out of 10 messages having the D over the check, or 7 out of 10 messages not having the D, but the other 3 do
