Telus Desire, is there a difference between HSPA and 3G?

[Lacrimosa]

I have my Desire on the Telus network, and I noticed that the icon on the top bar shows and "H" instead of 3G.
Is 3G the same has HSPA? I know Telus runs the HSPA+ network but I'm just wondering if there is something wrong with my settings or device.

GPRS
Edge
3G
HSPA

These are shown as G, E, 3G, and H respectively on the Desire's status bar.
