Gov. Josh Shapiro has signed a bell-to-bell ban on cellphones in Pennsylvania schools, MoreThanTheCurve reports. The Senate approved Senate Bill 1014 by a vote of 47 to 3. WHYY says Pennsylvania joins 26 other states with a statewide, all-day restriction. Bell to bell means the whole school day, so I suspect a few teenagers are drafting their objections right now. By text, probably.
