No more waiting on Froyo!! Thanks for the super simple instructions.
I spent about 40 minutes fighting with my PC (Windows 7) to make it work. Finally I gave up and went and stole my mom's laptop (she has my old laptop with XP still on it). It didn't work at first but then I remembered she didn't have HTC Sync. I installed that, rebooted the laptop, connected my phone, ran the installer and BAM! I got Froyo in about 6 minutes.
Now I am on my way back home and will spend the rest of my night resetting up all my apps and folders and icons and blah blah blah... this could take hours. LOL
