Weird, the iPhone 4 test devices in my office on iOS 7 are sluggish to the point of unusable. I guess they get used in a different manner than a normal user since they are test devices, but still, I'm shocked to hear an iPhone 4 being called 'fast', even with iOS 6 - I would say extremely slow with 7.
