T-Mobile HSPA is now on in Ukiah, Redwood Valley and Hopland (both former EDGE areas) up here in Mendocino County in NW CA, so that makes HSPA on now in Ukiah, Redwood Valley, Hopland and Fort Bragg in our county. Former Metro PCS LTE is available in Ukiah as well. All of this can be seen on Sensorly and RootMetrics, but T-Mobile's maps are only showing the HSPA in Fort Bragg. I will confirm more as I encounter it or find out new info.As far as HSPA speeds, they're not very good, it's definitely a lack of backhaul.Here's a speed test from my place I Redwood Valley, it was done from my Nokia Lumia 521-
