"Modern cell phones are not just another technological
convenience. With all they contain and all they may
reveal, they hold for many Americans “the privacies of
life,” Boyd, supra, at 630. The fact that technology now
allows an individual to carry such information in his hand
does not make the information any less worthy of the
protection for which the Founders fought. Our answer to
the question of what police must do before searching a cell
phone seized incident to an arrest is accordingly simple—
get a warrant."
