IMPORTANT!
Before you proceed, you need to understand one thing: although these upgrades work in 99% of the cases, you are doing this at your own risk!
If you have any problems or question with rooting and flashing ROM's DO NOT open new thread, cause I will delete it, post everything here

Before we start, here is little Q&A section, so please READ this before opening new thread!
How to format and partition SD Card?
Read this
Is my desire already rooted?
- Check if you have superuser app in the app list all rooted phones have it
If I root a device which is already rooted, can it mess anything up?
- You can't mess anything up by re-rooting.
Will my phone get the OTA froyo update from HTC here in the US or do I have to do it manually?
- No OTA updates when rooted, to get them you will have to go back to stock to get the update(yepp unroot, or wait for devs to release rooted stock version)
What is S-OFF?
-HTC implemented security on their newer generation phones. This flag, called @secuflag, controls whether your phone has
it's NAND or flash unlocked. Most noticeably, S-ON (security on) will read-lock your /system and /recovery partition, to name a few. Also, secuflag controls whether zip files being flashed through recovery or fastboot, are signed by HTC. The now notorious S-OFF (security off) will disable this NAND security. Since we are unable to access the Radio NVRAM itself (where secuflag is stored), we turned our attention to HBOOT.
Here is How to S-OFF your HTC Desire

There are several methods of rooting device and one of the safest is using Tiny Core Linux(Live CD), since I had several problems using Windows(64-bit) I recommend this option, but if you are using 32-bit OS you should be fine rooting in Windows.

Guide how to unroot, flash ROM and updates

fake-flash
Fake-flash is only possible with root access, you need to be rooted to use it. Basically, its a way to have recovery running on the phone without using a PC (making it safer as you are less likely to brick using no USB cable to push files, instead, you push directly from your phone). You can use "ROM Manager" from the marketplace to do this. Simply place the downloaded test recovery image on the phone and the downloaded rom zip (renamed to update.zip) and flash using ROM Manager.
Preperation

• Download the fake-flash update zip from one of the links below
• Copy the update.zip to the root of your SD card (the name MUST remain as update.zip)

When you want to launch the recovery image

• Turn on your device with 'volume down' pressed and select 'Recovery'
• When the exclamation mark appears, press and hold 'volume up' then press 'power'
• Select the second option, 'Apply sdcard:update.zip
• That's it, ClockworkMod recovery should launch!
