Hmmm. Perhaps we should start a pole, to see if anyone has got a HSUPA connection or not (by checking 'connectivity', mine says "T-Mobile Internet (HSDPA)".
Also, what's the point of launching it, if no-one knows how or if they are using it?
Found it myself. In registry go to:
HKLM\Software\HTC\AdvancedNetwork and change the key "SupportHSUPA" from 0 to 1.
Then go to Settings > Connections > Advanced network. You will see that this has changed from a simple tick box, to a full drop down. In the drop down, set to "Enable HSDPA/HSUPA".
Havent actually connected to any HSUPA yet here in Birmingham UK, but here is hoping that others will! Let me know!
