I got mine from Dell UK, unlocked. I installed the official update from here. This is the newer Nov 5 build.
Now running 2.2. It feels better after rooting and removed all the junk apps.
I have 2 niggling problems:
-the phone unlock slider sometimes does not work, making you lock and retry a few times.
-Letters typed from the keypad sometimes doesnt how up. But have observed this in the 3-UK Skype app only.
Other than this, 2.2 is pretty good and also seems to have better battery life.
