BJII - viewing unread messages only

[cda]

Hi,

I have a Blackjack II. Does anyone know if there is a way to view only unread messages in the text message or email window? In other words, a filter so that messages marked as read will not be displayed.

Failing that, is there a way to jump/scroll quickly down the message listing? Like a page down function? Or jump to a certain date?

Thanks for any help,
