I got my Tmobile iphone 5 the day they were released and up until this week I was getting pretty decent 4G speeds in DC. Anywhere from 5-13 MB down using speedtest. (Have yet to see LTE, but that is another matter) But the last week or so in the exact same spots I have been getting about 0.5 MB down. Is it just me or has anyone else noticed this in the DC area as well?
Outside of DC I don't have a problem.
