I still use the 64GB iPhone 4S that my dad gave me as a graduation present in 2011. It's great: nice camera, USB sync, Third Rail battery case, small screen, enough space for offline maps/music/Wikipedia and 300+ apps, and lots of jailbreak tweaks including OS downgrading. I bought a used 32GB iPhone 5 from my friend who wanted to get rid of it, but I prefer my 4S for daily use (including this comment).
