Have you asked to have the stipulations removed? I have heard of people doing that as a negotiating tactic (and succeeding). The worst thing they could say is no...
They probably won't check your pockets but it's still not worth the risk. If you were ever found with prohibited items you'll get reported to LSAC and schools will find out which really doesn't look good.
You shouldn't bring **_any_** prohobited items. If you think you need your phone to get a Uber/Lyft, you should think of other methods of transportation.
