However as many other people I still do not have one yet. So fro the inpatient here is a tutorial how to install it yourself.
1) Installed official Android 2.3.4, 2.3.6, 4.0.3. To update manually to 4.0.3 from any version check here: http://andwise.net/?p=70
Note that this is not a full update but a patch so you really need to have original(not modified) 2.3.4, 2.3.6 or 4.0.3 installed before.
2) CWM recovery, you can check how to do it here: http://andwise.net/?p=268 (only if you are updating form 4.0.3)
3) download the update from google (we will call it update.zip):
for 4.0.3(IML74K/XXKI1 Radio)->4.0.4 - http://android.clients.google.com/packages/data/ota/google_crespo/hR7QFEtn.zip
for 2.3.6(GRK39F/XXKF1 Radio)->4.0.4 – http://android.clients.google.com/packages/ota/google_crespo/fL9fwa99.zip
for 2.3.4(GRJ22/XXKD1 Radio)->4.0.4 – http://android.clients.google.com/packages/ota/google_crespo/RYyRmqNv.zip
Note: these are for i9020T/i9023, for i9020A from 2.3.6(GRK39F/UCKF1 Radio) use : http://android.clients.google.com/packages/ota/google_crespoa/IEzMw3FU.zip
