Nope. Best you can do is report the theft to your carrier and Apple so that your phone is flagged in their systems as stolen.
Does anyone know how the "location my iPhone" feature in the new 3.0 software works? I know its a MobileMe feature, but I was wondering if this can help if your phone does get stolen?
There is a remote-wipe feature for corporate customers. It is probably possible to get this activated. Maybe talk to Apple. It's probably just a special email or txt message. Doesn't bring your phone back thou
