42 Mbps is nothing to sneeze at.
Not all of T-Mobile's smartphones support the fastest HSPA+ speeds.
LTE does not always mean faster; just ask MetroPCS users. LTE vs. WiMax vs. HSPA+ vs. CDMA vs. GSM etc, etc, etc is just comparing protocols and modulations schemes. Some are more efficient than others. Speed is a completely different topic.
