I'm using straight talk AT&T sim on my iPhone 4S and always see 4G even in remote areas I have switched to edge but never just 3G has AT&T upgraded to HSPA basically everywhere or does it always show 4G even if their is only 3G?
I am a little confused. My Verizon phone was able to roam on GSM because they used TDMA. Tell it was shutdown. The phone recognizes it as Analog. If PCS has TDMA, It could be technically be used on GSM.

There is like a 200 page thread on here with people arguing about it. But yes, the "4G" indicatior does not actually indicate when you are on a "4G" network. 4G is the new 3G, with AT&T's 3G network, according to the iPhone, getting completely upgraded overnight.
This is only an issue on iPhones on the AT&T network as AT&T some how strong armed Apple into doing this... Some other AT&T phones do this as well from what I understand.
As far as I know all AT&T phones that were "marketed" as "4G" phones do the same thing. However, compared to the number of iPhone 4S's on AT&T's network, it was a pretty small issue and few recognized it. Making the iPhone 4S display "4G" falls within AT&T's messed up definition 4G, which doesn't make it right imho. Nothing more than a marketing tool, I'm really bummed Apple went along with it. I could go on, but to avoid a few more paragraphs of my ranting, I will stop here.
Displaying "4G" when connected via HSPA+ is acceptable under the current definition. The problem is that iPhone 4S displays "4G" even when connected via HSPA, HSDPA, or even UMTS, which is definitely not acceptable under any definition.
If anything Apple can strong arm AT&T. I'm not buying that this was just AT&T strong arming Apple.
If Apple was strong arming AT&T it would be the iPhone 4G, Apple publicly admitted that AT&T asked them to change it to 4G.

Not really, you could look in Field Test to see if you are on HSPA+, but there are areas that "are" HSPA+ but do not have Enhanced Backhaul. For example, all of the 3G in Western Kansas shows up as an HSPA+ network, but only a few areas supposedly have Enhanced Backhaul. Real world doesn't always back that up, which is why the whole "Enhanced Backhaul" thing is so badly defined. AT&T hasn't really stated what they consider Enhanced Backhaul. I can break 8-9 Mbps during the day in some urban EB places here in Kansas, but not break 2 Mbps in Rural EB places at 2 in the morning. There is no denying it is an upgrade though. With that said, currently the only way to know is to look at AT&T's coverage map an compare it to where you are. The irony of course being AT&T's own coverage map is inconsistant with what their "4G" phones represent their network to be, of course this isn't knew, AT&T displays all roaming coverage as "AT&T" making one believe they never roam.
AT&T is the only carrier that I know
of where the iPhone does this. So clearly it is an AT&T driven issue.
At&T and T-Mobile are the only two carriers in the US that has a 3G network that wasn't designed for dialup speeds like the CDMA carriers. I do think the iPhone should only show it is on 4G when it actually has a HSPA+ connection of 21Mbps or faster.
