I live close to Southfield, on the northern edge of Livonia, and while I can't figure out if my iPhone is connected to eHRPD or not, I've done a few speedtests and hav gotten speeds in this order
Ping: Down: Up:
86ms/1.28Mbps/.87mbps
67ms/1.49Mbps/.81Mbps
88ms/1.18Mbps/.87Mbps
Pretty fast to what I get in Ann Arbor which is usually
~300ms/~.60Mbps/~.30Mbps
