The policy that I think is better for the cell phones is the first because we could use the phone to ask question like in my case I forget thing and i could ask one of my friend to help me with the homework and if there a problem i could call the police and during class is good idea to turn them off because at some point phones are going to distract students from learning the subject or to study for a test and if you don't have a computer you could use your phone like for an example my phone I have the iphone 4g I don't have computer but i could go on the internet and search what my question is a video to show me how to do my projects.
