i found a aDSL number for ATT that was not advertised (and you reached a person on the first minute!) that was the result of some obscure regulation that they had to provide dsl without charging for a phone line if so i wanted. it was a very good service. as i was next door to their trunk.
i moved, less than 20miles, but another city. called att to transfer service, the rep read something and the burst out a sad "ah, sorry, this is verizon territory".
and that is exactly what i get here. verizon. nothing else. the 2nd or 3rd biggest city in los angeles, and i can choose, verizon.
