Is your Wi-Fi connection fast with your iPhone 5?
I've got an iPhone 5 and its Wi-Fi connection should be very fast, as Apple said. Nevertheless, my iPhone 5 in Wi-Fi is slower than my pc (Windows) that is 6-7 years old. Especially in YouTube, it's often impossible to me watching HD videos, because it loads them too slowly. Is it normal? If I took my iPhone to an Apple Store, they wouldn't find any problem, because it's an occasional problem; some days it's "fast" (normal), some days it's slow. That's very annoying! I've also installed today iOS 6.1 but nothing has changed.
