I was in the heart of DC in August 2004, and my phone worked great!

Are you concerned about a particular area of DC/MD/VA? I live in NVA and commute to DC, and I have been more than satisfied with the coverage (I had ATT a couple years back and it was horrible). I work with people that use other carriers and I find we all get comparable coverage. Verizon users typically have a slight edge in the elevators for some reason, but around town and in the metro area I'm usually 3 bars or better on my V300. There are some small odd areas (i.e. George Washington Pkwy) where I'll lose a signal for a brief period but it isn't too bothersome. Let me know if you have questions.

I used to live in the DC/Baltimore area (Rockville, but I spent a lot of times in both cities) 2 years ago and I still visit often. I have a Verizon account and a T-Mobile account and I can tell ya honestly, that while T-Mob isn't that bad in DC or Baltimore it isn't quite as good. I have found that T-Mob works better in certain parts of the suburbs especially north of Rockville. However, in the cities Verizon is better hands down. I believe Verizon's frequency has better building penetration which comes in handy in cities. But the kicker, to me, is that my Verizon phone works on the metro. I get a signal in almost 100% of the tunnels whereas my T-Mob is a useless brick down there. Hope this helps.

I forgot to mention...I'm pretty sure TMo has a 14 day trial period. That's what I did before I switched from ATT. You can sign up and check it out yourself; if it doesn't work for you, just return the phone and cancel the plan.
