Came across this last night on the xda developers forum... everyone thought it was an April fool's joke, but it isn't. I tried on my stock 2.3.6 i9020a Nexus S and now I have Android 4.0.4!! Sorry, I can't post links because this is my first post, but if you google: i9020a ics finally here xda It will be the first result, then go to Page 2 of the thread and you'll find the link. I've also PMd the admin to update the stickied thread. Enjoy!!
