So, I'll be getting an iPhone 4S tomorrow (should be a nice upgrade over my 2G :D) and it's on iOS 9. I've heard that the iPhone 4S is pretty slow on iOS 9 and fast on iOS 5 and 6. Is it possible to downgrade it? I can provide more details about the device tomorrow, sorry if I don't have enough.
Thanks!

It is easier to find an iPhone 4s with iOS 5/6/7 on it than trying to downgrade from iOS 9 to any older firmware.
