Verizon has finally started pushing out the update to Android 4.0.4 Ice Cream Sandwich for the Verizon Samsung Galaxy Nexus, or so that is what we are hearing the past 24 hours. If the update hasn't hit for you yet, or you're running a custom ROM we have the latest radio that comes with the update available for download.
Many Nexus users are probably still on the Android 4.0.2 update, and some might be using the leaked 4.0.4 from a few months back but the newest version rolling out today is said to seriously improve 3G and 4G hand-offs and improve signal strength. Users will see faster 3G/4G switching and in return -- improved battery life. You can wait for the update yourself, or if running a custom ROM (CM9, AOKP) or many other different ROM's you can simply flash the file below in recovery.
This is a ZIP and needs to be flashed in a custom recovery like TWRP or Clockworkmod, not fastboot, and will replace the CDMA, LTE, and bootloader files. As a warning the CDMA takes well over a minute so if it seems to be taking too long just let it finish. We are hearing this works with ANY Verizon Galaxy Nexus build and I've flashed it myself and seem to have similar results as before, but will report back later as I use it throughout the day.
