Sadly since I posted a work around to get the kindle app installed on a UK Touchpad the loophole has been patched, curses! 

However some lovely person has made the app available

After downloading the above file, All you need to do is open up WebOS quick install with your TouchPad plugged in (if you havent got WebOS quick install setup follow points 2-4 on this post).

Then click the big + button, find the .ipk, click ok and then click install.

You now have installed the app on your new UK Touchpad!
