Question: In Samsung OmniaPRO B7320, how to do sms partition?

In my phone all sms's comes in only one folder no partition for inbox, outbox etc, even i am not able to do this partiton. Sms's should automatically go to respective folders.Also sms's respect to one person displays as one sms with all received and our sent sms one below the other.Please help me to organise it well.
