I use iOS 6.1.3 on an iPhone 4S, jailbroken and running offline apps, syncing with iTunes 10.6.3 over USB, no iCloud.
It worked great 6 years ago, and it still works now. I'm not persuaded by the "updates" Apple keep trying to tell me to run; I think I'll lose more features and stability and battery life and USB sync, and not gain anything of any practical purpose to me.
If Android had USB sync, I'd consider converting. But swapping one cloud ecosystem for another just doesn't work for me, I want to keep my data offline.
