I dropped my new iPhone in water. It didn't know how to swim and drown. But I flirted with the Apple Store girl and she gave me a new one. Maybe someone will return your phone.
next time you'll have to jailbreak the iphone (which is totally legal today) and install iLocalis. bob lost her phone at wondercon and i used that to hunt it down. it totally worked. but also the person that found it was this nice girl that was totally going to take it to lost and found after she got out of the line she was in.
