I am a firefighter / emt and using the iPhone. I am careful to not wear my iPhone in any situation where heat or water are involved but running medical calls not a real problem. I like it because I can stay in contact with my businesss via email and during down times on shift surf the net and watch movies. Like it a lot. As mentioned in the previous statement I keep it in a rubber case when on duty and out of case when I am off. Hope that helps.
On a different note getting ready to start medic school in sept. any advice?
