HTC EVO Shift 4G
Why it's relevant:
The original EVO 4G, released by Sprint last year, was the first WiMAX-based phone in the U.S. and became a solid hit for the carrier. Sprint is trying to replicate that success this year with the EVO Shift model, which is much like the original but with the key addition of a slide-out keyboard added to the mix.
Although Sprint's WiMAX network isn't as speedy as Verizon's LTE network, it does deliver a solid download rate of between 3Mbps and 6Mbps. The long-term trouble for Sprint, however, is that device manufacturers will be more willing to make LTE devices in the future since Sprint is the only U.S. carrier to support WiMAX as its next-generation standard.
