ust having a meal break at work so taken a few minutes to try and help you with this
The phone must be rooted and
Install Busybox from android market
Install Titanium backup from android market
Install xrecovery from XDA
Did you try the x10HD version if not delete the one you have and give it a go first.
If the above is all done and you still don't have xrecovery then your phone system files are still read only if you don't mind spending £2 on an app
Install Root Explorer from the market then reboot phone.

Open Root Explorer and at the top will be a grey icon that says Mount R/W tap that so it changes to Mount R/O
Exit to your main menu and open xrecovery, now install xrecovery from there and you should get the 3 green ticks
Reboot phone into xrecovery and backup your current version as I mentioned in an earlier post above.
Volume button scrolls up / down
Back button is back
Home button is select
Installing 2.2
Download Beta3, Beta3 Hotfix and Gapps to your PC.

Connect phone to PC with USB and Mount the SD Card, create a new folder on your SD Card called 1Roms (this is so it appears at the top of your folder list).
Copy Beta3.zip, Beta3 Hotfix1.zip and Gapps 2801.zip into this folder on your phone from your PC then unmount the SD Card and disconnect the phone.
Step 1
Reboot phone into xrecovery
Select Install Custom Zip
Select Install Custom Zip from SD Card
You will get a list of your card folders 1Roms should be the top one open that
Select Beta3 and press the home button to install
When finished reboot phone and leave it alone for a few minutes.
Step 2
Reboot phone into xrecovery and follow above process to install gapps
When finished reboot phone and leave alone again for a few minutes.
Step 3
Reboot phone into xrecovery and follow above process to install Beta3 Hotfix
When finished reboot phone and leave alone again for a few minutes.
Step 4
Turn off the phone for a few minutes then boot phone into normal mode.
Download Titanium Backup from the market again and install it so you can restore your apps but as you have gone from 2.1 to 2.2
Install the app only don't install app+data as this has shown to cause instabilities.
Your done it now has 2.2 and you should not suffer from any issues, reboots, force closes etc
I would suggest that when you have installed all the apps and set them up turn off the phone, leave it for a few minutes then reboot
Once you have the system running after a day or so you need to backup the 2.2 version with xrecovery the same as the previous way mentioned above somewhere.
You will benefit from dual touch if you don't already have it from here
