Removing the "sent from verizon 4g lte"

Go to the inbox and hit menu then more then settings and then general settings and click the signature and erase it and save
 
When I am using "mail" I can remove it from each email account by going to Settings>General Settings>Use Signature. You can also change it to something different if you don't want to remove it completely. This process might be different or not possible for different apps, for example, when you use the facebook app it gives you a signature that says "sent from my android device" and I don't think there is any way to remove that.
 
go into your Mail app (not Gmail)

Menu>settings>General Settings>uncheck "USE SIGNATURE"

or

tap on the SIGNATURE area beneath that, showing "sent from verizon yada yada" and edit it to say whatever you want it to say.
 
How do you remove that Sig when using an Exchange ActiveSync email account? Don't see option to remove Signature under settings in that case....
