Not sure what the "R" and "D" mean either with the messages
the Busy system is completely opaque. I've read the RIM explanation several times and it doesn't make a lot of sense. Anyway, you can't declare yourself Busy, it's just something that your Blackberry indicates to others depending on your current usage.
D means delivered, just like with a PIN.
R seems to mean Replied or Reply Received.
