perl_user_52:

I use C, C++, C# and perl regularly. For the things you're talking about, I reach for perl first. It's great for cleaning data, it's easy to hook to databases, and it's the best language (IMO) for knocking together things quickly.

As far as writing apps for the iPhone, I don't have one, so I have no opinion on that.
