Yes, because they would have said 28.8 instead of 14.4.

The argument stems from the fact that the ITU did not originally define it as 14.4 Mbps (the lower end of HSPA+). I believe it was supposed to be 100 Mbps + fully IP based. T-Mobile and the other carriers muddied the waters when they started calling their tech 4G which didn't match the ITU definition. The ITU eventually backed down (because otherwise we'd be sitting at 3G way too long...bad for marketing.)
Impressive for sure, but why on earth would you ever need that type of speed on a smartphone?

HSPA+ can hit current LTE speeds. For all intents and purposes, the 4G marketing is correct because they are comparing speeds.
This will change, however, as LTE starts topping over 50Mb/s in a few years. By then, carriers LTE networks should at least be built out.
I think it would make sense to display it as '3G+'. I'm sure Apple had a reason for not touting 4G and I'm sure it's connected to the iPhone 5.
Unfortunately, it's not my phone It's some dude in Washington State (Link). I get 2Mbps on my AT&T phone (which seems to be what most people get on AT&T these days).
I bought my iPhone 4s on Verizon today. The only true 4G is LTE, so AT&T saying they're offering 4g is ludicrous.
Real 4G is non existent at the moment. MIMO technology is being used to have higher speeds but LTE and LTE Advanced are way too far at the moment. It's going to take a number of years to actually reach 4G or 4G-like speeds.
Don't know why AT&T would want a 4G symbol on the 4S when all their other pseudo 4G phones (HSPA+) have an H+ in the status bar?
As for the people reading Wiki articles and claiming they know what the 4S has or does not have, you will have to wait to get your hands on it and inspect the firmware.
The MDM6600 is an HSPA+ "capable" radio.
Whether it is configured to utilize HSPA+ standards is yet to be revealed.
This depends on whether Apple implemented HSDPA Release 5 or HSDPA Release 7.
If it's Release 5, it's HSPA, if it's Release 7, it's HSPA+.
I believe it's Release 7 (HSPA+) since they're claiming it's capable of 14.4Mbps down and 5.6Mbps up.
HSDPA Release 5 can't do 14.4Mbps. period.
And no, they can't be using dual HSDPA 7.2Mbps channels over MIMO either since it isn't part of the Release 5 standard.
MIMO came about with Release 7.
I don't think anyone even "needs" a smartphone, we seem to have done fine without them in the past.
It's all about want, and I can tell you I for sure want those speeds.
Release 5 tops out at 14.0MbpsAccording to the table at the link below, release 5 is capable of 14.4. http://en.wikipedia.org/wiki/High-Speed_Downlink_Packet_Access#User_Equipment_.28UE.29_categories
I still think its probably HSPA+. Other 14.4 advertising phones like the Atrix 4G claim to be HSPA+.

The ITU says HSPA+ is 4G, so what's the problem?
