If you don't want to risk being sued for a booby trapped phone, how 
about at least a way to render the it useless to thieves?

For instance, you could make it unbootable from a zero power situation, 
and then combine that with a rapid power discharge.  If the thief leaves 
it uncharged for even a day, its bricked!
