If the system doesn't provide a technical mechanism to require the 
warrant (PKI design for judges' signatures left as an exercise to the 
reader), then a warrant is NOT required, it's just suggested,
a SHOULD or even a MAY instead of a MUST.
That's especially true for the "poking around at what else is in the 
phone" side of the problem, beyond the parts covered in a warrant.
