So, the middle son gets the new Nexus 4, and I get his old GS. It is the fate of us old guys, but I'm happy, since it is so much better than his previous old phone! I had great hopes of rooting it, but none of the instructions worked, and you have to get the stuff from sleazy sites that want to load on a ton of adware. I don't think old phones can take new upgrades.
Still, not too shabby if you can still get all the bells and whistles. I got a great Jellybean keyboard designed for clumsy thumbs and poor eyesight. My g+ can still check in and I can use Instant Upload. Wow! The kids are just using all the modern stuff for games anyway. :) For that I have my Nexus 7.
