iPhone 3GS or Blackberry 9700?

[muck]

Looking at getting into the "smart" phone era....yeah, yeah I know...finally.

Biggest thing for me is email and being able to sync up to my Exchange server at work. I am aware that blackberry has "Blackberry Enterprise Server" software for this purpose. The iPhone must be able to do so as well... Does anyone currently run their iPhone sync'd with an exchange server? How is it setup?

Will I kick myself for getting an iPhone over the Blackberry if its mainly used for business?
