Long shot, but worth calling.
Omnipoint Communications Cap Operations LLC issued these blocks a while back. Most of the numbers are probably already with customers, but it's worth calling any you're interested in. If a number isn't in service, it might still be available at Omnipoint Communications Cap Operations LLC or one of their resellers.
