AT&T's HSPA+ network is faster than Sprint's WiMax network.
Hell, T-Mobile's HSPA+ network smokes them both.
AT&T's LTE network is supposed to be faster than Verizon's but it hasn't been put through any real world paces yet.
But the report claims sprint get's 4-5 Mbps download rates. This is pathetic.
I'm on AT&T's HSPA (not +) network here in Phoenix and I get 4 Mbps download rates.
Much faster when I go downtown and hop on their HSPA+ network.
