@rahasya, that's what I thought, may be I didn't have enough towers around me, but still managed to get good 4 Mbps downstream for a cellphone on speedtest. And, in my opinion, when it doesn't have enough coverage, and it flaunts like it has, it's 'overhyped' for me.
Some guy in Florida had his LTE speed crossing beyond 27Mbps, but here am in Santa Cruz and I had just 4 Mbps, and my area is  well-advertized for 4G LTE, These people still think they can blow the trumphet and sell their stuffs when it's not the truth.

Yeah.. ha ha ha.. another thing, these network providers give you services with pathetic data limit like 2/5/10 GB and then offer you 4GLTE, damnn.. you'd use that up all at once, and then what? It's like bigger pipe vs, smaller pipe and so less water. I don't really get it. Thank god, I've grandfathered unlimited data plan on my verizon network, rooted and happy with my 6-10 Gig monthly consumption, they at times throttle if I do too much but by the time time, my month ends and cycle restarts :D
