I am implementing the do-not-backup attribute for my app for iOS 5.0.1 and above. And as Apple suggests, there is a different way to set the key for iOS 5.1 and above. I can test it for iOS 5.1 and above (that nothing is crashing) with the simulators available but hoe to test for 5.0.1??
No,I don't think you can get 5.0.1 simulator. The best thing would be testing your app in a iOS 5.0.1 device.
