Purchased a replacement drone

[RadRocket]

I finally found a P3S for a reasonable price and good condition. Before I take to the skies again I want to get familiar with my new P3S.
I noticed this one is Phantom 3 Standard (USA) . My first one was a Phantom 3 Standard ( C/N )
Does anyone know the difference between the two ?
Also I need to know all the latest FW and Go app versions

I think we need to know just what firmware your running now..its a big debate here on updating and Not updating...My P3SE is 9 nine months old and ever thing works great...as i have never up dated the drone.
