AT&T Misprint or Apple's Just One More Thing?

Did someone from AT&T goof when they posted these or is this Apple's way of saying "just one more thing"? Last I checked, the iPhone 4S didn't offer LTE compatibility on AT&T's network, but it wouldn't be the first time Apple snuck some hidden technology into it's devices (anyone remember the Bluetooth chipset that was secretly included in the first generation iPod touch, even though it wasn't advertised? I do.)
