A few months ago I upgraded my iPhone 4 from iOS 5 to iOS 7., then more recently updated it to iOS 7.0.6.
It's definitely faster than on iOS5, plus more overall speed because of the improved iOS interface.
Most of the time I use WiFi, my carrier's 3G speed is only good after midnight. Their daytime 3G speed started dropping rapidly about 2.5 years back, obviously too many phones using it.
My iPhone 4 does the job very well for me, mainly basic investment info and news. It more than pays for itself.
Videos are slow, so I avoid them. The now popular investment videos are not that useful anyway, mainly advertising.
It will be used until failure, still gets an average of 4 days per charge.
