A coworker's wife is doing her residency in med school and he said there is an app she relies on hugely that shows drug interactions, etc, but I can't remember what it's called. I'll ask him on Monday though and post back.
Probably Epocrates. There are a lot of pharmacopeia-type apps, but Epocrates is the most popular, probably because it's a free download. I don't have an iPhone, but I know two of my colleagues have ditched their Palms for iPhones and have everything they used to use, and more, so there's definitely plenty out there. What you'd specifically use most would depend heavily on your specific field.

You do medical school first, and then, after graduation, do a residency.

Also- I don't really know her situation, I'm just repeating what he says. She hasn't graduated yet though so maybe it's an internship, I really have no idea.
I have a SmartPhone (not iPhone) and have Epocrates (I have the free, basic version and it's all I need), Taber's Medical Dictionary ($49), and Diagnosaurus (lists differential diagnoses, also free) on it.
I'm a Physician Assistant student and have found all 3 applications extremely useful while on rotation! I have to say that I used Taber's more in the classroom than on rotation, though.
