last time I checked at&t's 4g phones weren't getting faster down or up speeds than the iphone 4.... The iphone 4s can do 14.4 down...

how is this possible? i thought 3g ended at 7.2 mbps?:confused::confused:
 
Who said the iPhone 4S was "4G"? Not Apple. Maybe ATT who is calling their HSDPA+ "4G," even though it's 3.5G, but Apple is clearly not marketing the 4S as a 4G phone.
 
The iPhone 4S supports HSDPA, which is considered a 3G tech and runs at speeds up to 14.4 Mbps.

Read what you link to.
Standard HSDPA (HSPA) runs up to 14.0 Mbps.
The iPhone is an HSPA+ (evolved HSPA) device as it runs HSDPA at 14.4Mbps.
The ITU changed the definition and said providers can call HSPA+ 4G.
From a marketing perspective, it's 4G.
Reality, it's 3.75G

We all know AT&T and T-Mobile call anything using HSPA+ a 4G device.
Hell even Verizon and AT&T's LTE deployments don't meet the 4G spec.
They're 3.9G
Sprint's WiMax is only 3.75G and is slower than HSPA+.
