Thanks for the reply, but I guess I'm a little confused. When I go to the link below and tap the arrow to turn the pages to the right, I see Chicago listed for 4G and 4G LTE coverage (I know the 4S is not LTE of course).

Also, when I go to the AT&T site for 4G phones, the 4S is the first one listed and says 4G.

I'm just wondering if it will be faster for me from a data standpoint than my iPhone 4 and if so, how much.
At this point, 4G has become a marketing term, rather than any real indication of the underlying technology. Most 4G phones I've seen advertised are using the same technology as the iPhone 4S does on AT&T's network. The rest are either Sprint's WIMAX, which is certainly fast, or LTE, which is also quite fast, but not actually 4G.
It's unfortunate, but standards bodies and carrier networks have been very slow to adopt emerging technologies, so we're still quite firmly stuck with 3G, 3G+ technologies.
The iPhone 4S is going to have faster data, under certain conditions, than the iPhone 4, iPhone 3GS, and iPhone 3G. It will always be faster than the original iPhone. These are good things. But, it does depend on your network, the towers you have nearby, and largely is a marketing term. AT&T has decided to use the 4G marketing term for this and other phones, but that's all it really is. HSDPA 14.4 Mbps is certainly better than regular old HSPA 7.2 Mbps. As long as you understand that, you can call it whatever you want, really. It is
not HPSA+ though, that is considerably faster than both, and only really T-Mobile has adopted it, as I recall.
