Tom, this will require the execution of any of three conditions:
1. Passing an electric current from a distance.
2. Physical teleportation.
3. Quantum teleportation.
How I would very much like to help you, but to date any of this is impossible.
If you have lost it at home or at a friends house - remember where you saw the Iphone was the last time, and look for it.
If you suspect that it could steal, follow the prompts from 3 to 6, which are described in detail in our Hyde "What to do if your iPhone is lost or stolen":
3. Disable the SIM card
4. Change your iTunes Password
5. File a Police Report
6. Notify People of the Missing Device
Good luck for you, Tom!
