You should try to go to your local service provider's store and have the phone blacklisted. If someone tries to sell it, then it could come back to that person. Also, they might have options for you, however as posted above I believe you are probably out of luck unless you have a third party GPS app or SmrtGuard.
I was going to mention that too Johnceef, its best to call your missing phone. But a phone like the storm will always be between the car seats or sofa.
