corporate department logo

We need a logo for a corporate department. The department is "Application Support". This department supports large-scale applications that have 100+ users as well as blackberries and other wireless devices. We're open to designs, although we would like for it to be more reserved (as opposed to funky or eye-popping). The final product should be a vector-based format, preferably an .ai. You're welcome to use whatever colors you would like, as long as a black and white version is also included.
