The VS840 is the LG Lucid according to a quick Google search.
To check which version of Android you're running simply go to your settings menu, scroll to the bottom, and select "About phone" (if your setting menu is skinned this could be slightly different). You should then see all the pertinent info about your phone including the Android version, kernel version, and build number.
My Nexus S for example shows the following:
Android version: 4.1.2
Kernel version: 3.0.31-4-bln-voodoosound-bigmem-crtoff-powerhal-gbc75230fschaefer@pc-florians#1 Tue Oct 16 09:29:04 CEST 2012
Build number: JZ054K
This shows that I'm running the latest Nexus S friendly version of the OS with the latest Nexus S radio, and a custom kernel with a few extra features written by some guy named F. Schaefer.
