I am looking to purchase a PDA for school, I could use a new cell phone so I was thinking that I could look at the smartphones. Then I read on here that it might cause some conflicts with schools/hospitals not permitting cell phones. Can anyone tell me if CSN/Hospitals have any rules or restrictions on the use of smartphones? And also what about just turning the phone off, then it is strictly a PDA? Any info would be greatly appreciated. I am looking to buy my PDA/Smartphone or whatever this weekend, so please reply!
