User Guide for the Samsung Galaxy Nexus is up on Verizon's site18
For those of you who consume all things Galaxy Nexus, you can now take a look through the official User Guide that is up on the Verizon site. It doesn't go into great detail, but does cover the basics, such as using the camera and setting up wallpapers, and also has some information on beaming screen content through NFC and optimizing data usage to help prevent going over your data allotment.
Hopefully it won't be too much longer until Verizon officially announces the release date and pricing (which is expected to be $299 after rebate with contract).
