Can I downgrade my IPhone 4S iOS 6 to 5.1.1?

Can I downgrade my IPhone 4S iOS 6 to 5.1.1?

I don't think so, once you've updated it's permanent

Yes definitely!

I've done it before cos I didn't like the way the IPhone 4S 6 ran, I preferred the 5.1.1 as well so…

Just enquire with the company and they'll be happy to sort you out!

I don't think there's any option to downgrade but still you may ask to service center, may be they will help you out!

Yes, you can downgrade it, but the thing is you have to have your Iphone backed up onto your computer from before ios 6.0.
