This is what I used:
GSM Nexus Owners (AT&T/Rogers/Telus etc.) can get it here :

Also, for those who do not know how to update manually:
Rename the downloaed file to update.zip
Put it at the root of your SD-Card and then turn off the phone.
Hold down the volume button and then press the power on button, it should go into a boot screen. Wait for a few seconds for it to load up proper and then select "Recovery" with the volume down/up button and press the power button.
Once you see an android holding a sign with an exclamation mark push volume down+ volume up + power button _at the same time_.
Select "apply sdcard:update.zip"(or something similiar) with the trackball and press it.
After the update is finished select "reboot system now" with the trackball and press it.
Wait for it to reboot, it can take a long time mind you.
