Yes. About 2 months ago speeds suddenly dropped from 15-20Mbps to 0.1-0.3Mbps. I'm in Michigan, close to Ann Arbor. What's really weird is that up until 2 weeks ago the coverage map showed my home area to be in a dark green, "excellent" area. Then a week ago the map was updated to show that I now live in an edge only area. They took away the HSPA coverage! Of course T-Mobile refuses to answer my inquiries; each time I ask they tell me nothing is wrong on their end. Also, even though the map shows no more 3G here, my phone still shows full bars of 3G/H. And the speed is still very slow.
