I worked for \\\ - we were doing network support and deployment for the yellow cell carrier, I in particular worked on network gear made by a Korean company.

Surprisingly I'd love to work for a large telecom again, I enjoy the work, and surprisingly even the large corporate environment, plus, I'm in the PNW right now, and I'd like to relocate to 'not here' (Ideally DFW, but I'm not picky, just someplace warmer).
