Just been to my local Apple Store to have my faulty iPhone 5 replaced and I've been given one with iOS 6 on it! They offered to update it there in the store but I told them I'll do it later at home. After being so used to iOS 7 (having gone through all the betas) it feels quite weird using iOS 6. The few changes I really miss are: - Control centre - merged address / search bar in safari - multitasking - overall UI Everything just seems so dull and old fashioned on iOS 6. Will be upgrading back to iOS 7 this evening, just thought I'd share my experience.
