BB Curve 8900 :: Contacts Are Undiscoverable

I have got a 8900, in India and am using the data plan to monitor my personal emails.Problem is that 'contacts' shows *no contacts*.When i go into options of contacts to sim phone book, (Contacts> sim phone book) i can see about 25 contacts. I have tried to copy all contacts of sim phone book but it still doesnt show up in contacts ( Contacts> sim phone book> Copy all to contacts). When i click on this, a status bar goes to 100% in a second, but contacts still show *no contacts*

I have saved many contacts on this handset through call register and messages and hence when i go to (Contacts> options> contact lists>defauly) the number of entries shows 320. I have noticed it increases as and when i add new contacts.Still no contacts shown in 'contacts'. Hence have to dial each contacts number before making a call or search from call register. Can someone pls help me with this. Also meanwhile if anyone could help by letting me know how i can make my call register remember calls of say last 10 days or 100 last entries.
