I think there's some confusion that needs to be cleared up. It's interesting though that the http://www.omnicitycorp.com link takes you to the http://broadbandnetworks.com/home/? link. Also, according to the following description on Bloomberg BusinessWeek it was Omnicity Corp that changed it's name to Broadband Networks Wireless Internet and now operates as a subsidiary of Broadband Networks Inc..
The guy that you talk to don't understand how a public company works,OMCY is the stock symbol not the company, the company is Omnicity and Omnicity applied for the symbol and never canceled it after the BK.
