as usual: you might brick your phone if you don't know what you're doing! so don't!

just a short list what I did to get my htc desire (t-mobile branded) to do what I want it to:

  1. Create Goldcard:instructions
    I used diskutil on OSX to flash the goldcard image to the sd card like this:
    diskutil unmountDisk /dev/disk2
    sudo dd if=goldcard.img of=/dev/disk2
    diskutil eject /dev/disk2
  2. download the bootloader 0.8 flash stuff from modaco and follow the guide (this should give you root)
  3. use unrevoked^2 to permanently flash a recovery image that allows you to do nandroid backups and flash roms
  4. flash whatever tickles your fancy
