Google a program called Mobile Sync Browser. Great app for PCs, don't know if it works on macs but probably does.
 
and if you're on a Mac, there's a program called PhoneView by Ecamm Network. I think its around $20, and it lets you view/archive SMS, Call Log (even shows call duration! why cant the phone?!), and allows you to view/edit notes too. It's pretty sweet. I highly recommend it.
