GSM version has 4.0.2 update, but not pushed over.
i have manually downloaded the stock image from google and manualy flash it.
i am now running 4.0.2
http://code.google.com/android/nexus/images.html
what i did was,
backup my system (just incase).
Factory Images "yakju" for Galaxy Nexus "maguro" (GSM/HSPA+)
(all file extract from the 4.0.2 (ICL53F) image)
flash bootloader
flash radio
flash recovery
flash system
and reboot, and presto. you are on 4.0.2.
my experience, this does not remove all your data.
just similar to a upgrade for me.
a side note. i am running everything stock..
Any idea how well that would work on a phone currently running yakjuxw?
