Problem Unlocking UK Voafone HTC Magic....

[dreamsofubuntu]

I'm following the CyanogenMod Wiki but I cant get the first part to work I've downloaded the sappimg.nbh file and copied onto the sd card and booted the phone into safemode? (the bit with the skateboarding droids...) and I can get to step 5 but trying to flash the image gives me the error:

  Parsing...[SAPPIMG.nbh]
  [1] RADIO_V2
  [2] BOOTLOADER
  [3] SPLASH1
  [4] RECOVERY
  [5] BOOT
  [6] SYSTEM

Model ID incorrect!

Do you want to reboot device?
<Action> Yes
<Power> No

As I've said It's a United Kingdom HTC Magic from Vodafone which are 32B devices

Thanks in advance!
