WCBS-TV is, indeed, on the air, apparently from the Empire State Building. All other major analog TV stations appear to be off the air.
WCBS-DT and WNYW-DT were located at the Empire State Building. The others were at the World Trade Center.
I am located about four miles north of the disaster, but, even here, phone service comes and goes, so, if you can’t get through to people, it doesn’t necessarily mean the worst.
Transportation is also very difficult. There is only limited subway service. All bridges and tunnels are shut. There are no trains or subways into Manhattan.
