T-mobile have been promising for 18 months to correct problem. Today, April 29, 2009, coverage started getting worse at Hwy-7 / 28 interchange

I get a bar to no coverage in my basement--depending on where I am. Upstairs, I tend to get one to two bars, but one time I had three. Four bars is something I rarely see save for major areas like the Dulles mall and Tyson's. Also, there is absolutely no reception at Broad Run High School, which really drains down the battery. In comparison, my friends on AT&T get perfect reception at school and around town.

I live near Gloucester Parkway,ashburn,va and I get no service in my first level of home.

Been in same townhouse for last 2.5 years and service seems to have improved from poor to average..though the bottom floor of my townhouse will usually only have 1 bar

I used to get 3 bars but not any more.

The stretch from Loudoun County Parkway / WaxPool intersection to Loudoun County PArkway / Ryan Rd.intersection has really bad signal. I contacted Cingular and they said that they have project going to covert some At&T towers to Cingular and that might be causing the issue.

Inside the industrial buildings on Filigree court, there is really good signal... . almost perfect. So far this is the only known carrier that works inside buildings in this area.

Reception with Verizon Wireless is quite good in this area but entering large structure reduces signal to almost 0.

No problems at home. Usually get almost full or full bars on reception.

1 year in and it 's a good day if I get 2 bars in my 2nd floor house and 3 on the ground. I do get 5 when I'm in Sterling though. I get so many drops that I am VERY frustrated with T-mobile's coverage area. I am going to switch soon and recommend you stay away from them if you live here.
