Best iOS version for an iPhone 4?

[dj9928]

I have had to revert to my iPhone 4 while my main phone is off for repair, I have blobs for 5.1.1, 6.3 and of course iOS 7, for speed and stability which version is best for the iPhone 4?

Go with 5.1.1 I have that and it works perfect. I think it is the best one for the iPhone 4.

In my experience, iOS 6 was slightly faster than iOS 5.

I miss the days of ios5. Ios6 slowed down my 4s back when I had that phone.

Either 5 or 6 should do the trick.
