There were rumors the 2011 iPhone would have an HSPA+ radio for faster download speeds but when Apple announced the iPhone 4S, while they said it would do 14.4 mbps, they only listed it as an HSPA device. Some don’t believe that anything under 21 mbps shouldn’t qualify as HSPA+, so iPhone 4S shouldn’t qualify. However, 3GPP release 7 doesn’t mandate that faster speeds are necessary to qualify as HSPA+ — a device can support any 3GPP release 7 feature and be classified as HSPA+. The Qualcomm chipset in iPhone 4S uses 3GPP features, and so it’s an HSPA+ radio, speed be damned.
So while iPhone 4S did indeed get its HSPA+, it didn’t get the 21 mbps or 42 mbps speed to go with it that many were hoping for. Also, Apple chose to neatly sidestep the whole 4G/fake 4G issue, so we won’t open that can of worms here either.
