T-Mobile USA has doubled it's HSPA+ network speed to achieve theoretical peak download speeds of up to 42Mbps.

It needs to be seen that how does it compares with Verizon Wireless' LTE service. Verizon says that its LTE users should experience average data rates of 5 to 12 Mbps in real-world, fully-loaded network environments. Can T-Mobile's 4G network beat it?
