I've been on Crackberry for a while and I've never seen a topic of it, so I thought to ask...
Did you guys know that if you want to read what people write you and keep the "D" instead of "R" all you have to do is go to the chat history of the conversation, open it and read! I tried it on several different devies and it worked!
Another one if anyone's reading this, desperately needs to see something, doesn't want the other person to know and doesn't have chat history enabled, is just disable your network connections for a bit.
Obviously essentially useless given it's marked R as soon as you turn your network back on, but it works too.
