AT&T - America's Fastest 3G Network Getting Faster with HSPA 7.2

AT&T says they're America's fastest 3G network and Computerworld has recently confirmed it, but now it looks like they want to take it up another notch -- to HSPA 7.2.
The upgraded network platform could allow for theoretical peak speeds of 7.2Mbps.
And this well in advance of their planned transition to 4G LTE networking in early 2011. Curiously, AT&T updated their EDGE platform just before the original iPhone 2G was released, and their 3G platform was made -- okay, slightly less thin -- before the iPhone 3G launched. So whatever could be prompting this latest speed boost?
