Does anyone here work in a reasonably large enterprise that is supporting iPhones as a blackberry alternative? I work at a fairly large law firm (550+ lawyers) and some of my colleagues and I want to swap our blackberries for iPhones. Unfortunately, we are running into the usual resistance from the IT department. Has anyone got any tips on how to convince them it won't be the major pain they fear? Any examples of iPhone roll outs I can point to? We're running Exchange 2002 SP2 so there is no issue on having a compatible backend. I'm hoping it's just a matter of convincing them that setting up and managing the security policies won't be noticeably burdensome. To help in that regard, it would be ideal if there was an IT manager of a similarly sized institution somewhere in North America that I could point to and say: "Look, he did it. Why can't you?"
