any advice on cellular plans btw NY & DC? Hi, I've finally decided get a cell phone. I don't anticipate using it that much (famous last words?). Anticipated use: (1) fiancee (in DC) can call if I am online/on my apt phone (2) those little pseudo-emergencies (missed meeting someone, delayes in travel, etc. (3) To get messages when in DC where I work in a space with no phone. I live in Manhattan, spend approx. 1 week a month in DC and travel somewhere else in the country about 2-4 days every other month. Does anyone use AT&T, Verizon, or Voicestream in both DC & NY? Some say I have a soft voice, so sound quality is important.
