I been using the MT4G at the TMobile store and I can't tell if I'm on HSPA+...? When I go to settings and look at the network, it says "HSDPA". I'm not sure if this means I'm on regular HSPA or HSPA+. I live in Baltimore and I know we are supposed to have HSPA+. I ran speed tests using both the phone and the tmobile rocket in the store and It gets about 3Mbps down.
