I found it a frustrating exercise to get the patch for locking and un-locking the home-screen applets in place to work but I finally managed to do so and it seems to work well for me.

Since I'm a total Linux n00b and struggled a bit I thought that there may be others out there like me that would benefit from more of a step-by-step.

Disclaimer: Following these instructions is your own decision and I take no responsibility for anything bad that may come out of it :-)

Also, note, I believe that this is only applicable to OS2008.

1) Download the required files.
In this thread qwerty12 lists the three files needed.

Download them one by one to a folder on your tablet that you can easily get to.
Me, I put them on a folder on the internal memory card I had created named "Content".

2) Install the files
This does require a few steps.

a) Open up Xterminal

b) Give yourself root access (me, I use rootsh and issue the command "root" and presto, I have root access and can do things I most likely never should).

c) Browse to the folder you saved the files in.
I had mine in a folder named "Content" on the internal memory card so I did:
cd /media/mmc2/content

c) I then issued the command "ls -l" to make sure I was in the right folder and that the files were there.

d) Then issue these three commands:
dpkg -i hildon-desktop_2.0.18-1fix1_armel.deb
dpkg -i libhildondesktop0_2.0.18-1fix1_armel.deb
dpkg -i libhildonwm0_2.0.18-1fix1_armel.deb

3) Re-start the tablet

You're done. If you now go to the home-option (see my screen shot) you now have an option to toggle the apps to be 'locked in place' or 'movable'.

I love it.
