Usually HSPA+ is known to be a very fast adaptation of 3G. Sometime in 2010, T-Mobile called their HSPA+ as 4G. So ATT will follow suit this year 2011 and call their HSPA+ networks 4G as well. On the other hand, Verizon calls their LTE implementation as 4G. Ma-Bell, not to be left behind, now calls both their HSPA+ and LTE (to be rolled out in summer 2011) as 4G. This is a good example of marketing technologies to the point of obfuscating them. The above table will clarify the differences and what the actual speeds are – of course, end user speeds will be always a tad slower than what the technologies attempt to provide.
