take them all out of the inbox to a temp folder. then mark all as unread. then move back to inbox. problem is they lose the date formatting. when you get them on your bb, they will all have the same date - the date that they came into your bb. the only workaround i found was to change the date on my bb to correspond to the date that the email originally came in. not too bad cuz I only had 50 emails.
