This has been my gripe in the 3G world for years. Verizon saying their 3G network is better, when really there's no comparison because they aren't the same technology...
Why do we need 4G, when 3G hasn't even reached its peak yet? I typically see between 1.5 and 2mbps with AT&T, but HSPA+ is capable of 80+mbps. Providing even 15-20mbps on Verizon 4G when it's capable of many times that, is lame.
