Need to restore contacts from backup

[iPodOwner1]

I had an iPhone 3G, put my contacts in it through the phone.

I took out my SIM card one day, and the contacts were still in the phone, I thought I had saved them into the SIM card.

I restored my iPhone and it just backed up all the contacts back, which was good.

I returned my iPhone and the contacts are in the backup, anyway I can get them back?

PS. I have a iPod Touch and it put all my Music for the backup but not my contacts.

Sorry for the double post...but please help. I had many inportant contacts and I have no way to retrieve them.
