I've been monitoring the Sprint thread regarding the Galaxy Nexus and the issues with the 4.3 update - https://community.sprint.com/baw/message/731946#731946
The next to last post (from yesterday):
Thanks for the post. Sprint and Samsung are working on getting this fixed. Both companies are aware that there are customers that are having an issue with the update. Right now there is no official info that can be provided as a solution has not been finalized. Once the patch is complete Sprint and Samsung will update the devices. To stay on top of the latest goings on please stay tuned to our newsroom. www.sprint.com/newsroom

Looks like we may be getting a fix or two. I hope it's for the quick battery drain due to a flaky antenna firmware update.
