Just got confirmation with TMobile that they are experiencing problems with a tower in the Washington DC area zip code 20005.
Phone service is working, but unfortunately Blackberry Emails are being affected.

Users will only be getting a GSM signal instead of GPRS or EDGE.

As of right now TMobile engineers are working on the issue but there is no ETA on when it will be resolved.
