It probably won't help you land a development job, but the skills you can pick up in an IT job can be extremely useful. My first job out of college was working in a network operations center doing network and systems administration. We used to make fun of the developers that worked downstairs because half of them couldn't figure out how to install the tools they needed for their jobs. After landing a software engineering position, I turned around and used my experience to set up all sorts of infrastructure that helped manage our projects (e.g. new version control systems, continuous integration, issue tracking, shared storage, etc.) While the IT experience did not really help me get the job, it helped make me a key member of the team.
