I need to upgrade 5.1.1
My apps are closing automatically , I don't want this 6.0.1, I want back to my original 5.1.1, that's perfect with my phone
iPhone 4S, iOS 5.1.1, Apps are closing automatically.
This has happened with every iPhone OS upgrade there has ever been. You will just have to wait for the app developers to fix their apps.
It is not possible, nor has it ever been possible, to regress Apple firmware upgrades.
