iPhone 4S Gets Fake Upgrade to 4G

Marco Arment on iPhone now showing "4G" on AT&T:

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.

I can't believe Apple agreed to this.
