Mine didn't have the "Help" app either. To find the icon list, I went to the "HTC Mobile Guide" app (which took me to an online system) then I clicked on "Phone Basics", then "Status and Notifications", then "Status Bar". The icon list is there. Incidentally, the icon the OP referenced (little glowing house) is not on this list. Maybe there are differences in carriers in play here. Mine is Sprint.
