Thanks to the generosity of @128keaton there is an iPhone 4s in our house running iOS 6.1.3. Jailbroken! My son turns 13 in October and he needs a phone and this one will be his. Unlocked Verizon phone. I have a T-Mobile SIM on the way. I get to play with it and set it up a bit first though. Already got his iCloud ID (through Family Sharing) set up as well as Restrictions. Software Update Killer was the first tweak install. I miss iOS 6!!!!
