I have a Blackberry and loving it but: i have the following problem:
I have 4 messages (sms) that I cannot erase and I don't know why - the last message that is un-eraseable is one that I tried to send to a number that doesn't exist anymore so there is the red x sign saying it wasn't delivered - Maybe it has something to do with that?
It's weird as all the other messages after that particular message can be erased though
even if i open the complete menue where you can opt for the 'erase before this date' it is not erased.

it really pisses me off!
maybe someone can help me!
