I need some clarification....Will my Verizon GS3 be receiving Jelly Bean or do I have to root and flash it myself?
It will....when is the question. Rooting, of course you could have it now.
I thought I've seen a couple of VZW leaked builds, so I can't imagine it being too far off.
Just like vaping, there is alot of information you need to know before diving in and installing custom software/firmware on your phone.
Once you get a good idea of what you are doing, it's pure customization from there...just like vaping!
