Is the infrastructure in place to support this? I feel like the removal of payphones in public places makes me hesitant to support a smartphone ban of any sort. Yes, they shouldn't be in the classroom, but if students have them in their locker... I remember in junior high, my sister and I had a rather busy extracurricular schedule, and my mother couldn't always be counted upon to remember when events let out. Payphones were a good way to arrange transportation from various events. All those payphones are gone now.
Banning smartphones doesn't preclude having dumb cell phones. My smartphone died last week and I thought long and hard about getting another one. Ultimately I don't have the willpower to totally resist, but these last few days without one have been enlightening.
