Does Cingular Wireless have it's own network on LI and in NYC? If you were to sign up for a plan with them do they roam onto AT&T or T-Mobile or something? I see a couple of Cingular stores around here and I do network searches on my phone and there is absolutely no Cingular Wireless present in any of the searches here. Although in NE I find it quite a few times. Where's the orange guy around here? Does he use others?
