Not to be an ass, but there is a thread detailing exactly how to do so like 10 posts below this thread...
Anyway, follow these instructions - http://mybroadband.co.za/vb/showthread.php/256278-How-to-update-an-HTC-Desire-to-Froyo-Manually-%28No-root-required%29
Rooted and upgraded my Hero with the XDA dev 2.1 firmware (which was just an unlocked version of the official) and couldn't be happier. Rooting is absolutely worth it and far safer/simpler than 99% of people will make it seem.
Just get the firmware (google or search XDA developers I suppose) and follow http://www.roothtchero.co.uk/step1
Only advice is ignore the rubbish about applying the initial 100mb firmware (the "downgrade") from HTC's site. Doesn't work on local heroes and is unnecessary.
Best part about the Rooting is you can just backup your phone TO YOUR PHONE (via nandroid) forever after. Feels way more secure to me.
