Anyone with iOS 5.1 and an AT&T iPhone 4S will now see a 4G symbol in certain areas. The only problem? It’s not really 4G, it’s marketing BS from AT&T.
I can confirm: my AT&T iPhone shows “4G” now, and I just benchmarked the connnection at a blazing 0.63 Mbps down and 0.07 Mbps up.
It’d be more defensible if it only showed “4G” when it was actually hitting those 4G-like speeds, but it just shows “4G” in supposedly high-speed-3G areas whenever it’s connected to AT&T’s network at any speed.
