California and Florida, for example, have issued conflicting rules for the search of cellphones seized upon arrest, with the First and Seventh Circuits interpreting the law in different ways on the federal level. Ching, “Cellphone Question Headed for Supreme Court,” The Recorder (May 30, 2013); U.S. v. Wurie, ___F.3d___, No. 11-1792 (1st Cir. May 17, 2013); U.S. v. Flores-Lopez, ___F.3d___, No. 10-3803 (7th Cir. 2012).

Earls, No. A-53-11 (July 18, 2013), against the Fifth Circuit (In re Application of the U.S.A. for Historical Cell Site Data, No. 11-20884 (July 30, 2013), on the issue of cellphone location information.
