Top is the security feature:
The BlackBerry Enterprise Solution is built with corporate data security in mind. It features an end-to-end security model designed to seamlessly protect your corporate information from attack as users send and receive email and access data wirelessly*.
The BlackBerry Enterprise Solution safeguards the integrity, confidentiality and authenticity of your corporate data with a strong encryption scheme that keeps data encrypted while it is in transit between the BlackBerry Enterprise Server and BlackBerry smartphones.
iPhone 3GS for several reasons:
(1) I already have an iPhone, and I know that some of my favorite apps are unavailable on the BB
(2) I like touchscreens
(3) iPhone works better for certain kinds of enterprise-level applications like Microsoft Exchange (email and calendar)
(4) I did some development work for the Blackberry platform, and they do things so backwards that I can't imagine ever actually owning one
I actually planned on buying the new iPhone, but I recently found out that I'll be getting a free Windows Phone 7 from work, so I'm going to try it out, and, if I like it, I'll stick with that. (It's a complete rewrite of the Windows Mobile operating system, so it won't have a lot of the weird quirks and problems that Windows Mobile has had in the past. I actually saw a live demo of one of the prototype phones yesterday. It looks good, but I'd have to get my hands on it and play around with it to see if it does what I need it to.)
