I have an iPhone 4 with iOS 5.0.1 Jailbroken with sn0wbreeze-v2.8b11 and my settings are not working. I set display battery percentage and the little switch says ON but it doesn't show and when I click my home button and go back to settings it's OFF. The same issue is present in ALL of my settings.

I have re-installed iOS 5.0.1 and re-jailbroke it but the results are the same.

Any ideas?
