What is my iphone 5's firmware?

I'm trying to jailbreak my iphone and i need to know what firmware i have? How do i find that out.

Your iphone's firmware is iOS.
To see the firmware version go to settings>general>about and scroll down to "version" and that should say something like 7.1.2 or 6.0.1
That number is the firmware version.

Also -Pro tip; be patient during the jailbreak process, on my first try I was hasty and unplugged my phone too soon and messed it up completely.
