I have noticed ehrpd in knoxville, Sevierville latley. No difference in speeds but 3g speed in this area are pretty good anyway. Knoxville use to not be but about a few months ago it has really sped up. I'm waiting on 4g to just to say I have it but will probably keep it off mostly as i hear it is a battery killer. I have never really had a problem with sprint and I think they are much cheaper than att/verizon and if you get good 3g speeds than it is a better deal. Also I have called sprint a few times or accounts and other thing and i tell you what, They might lie to you but they are always nice in doing so. Always an english speaking rep and extremely nice I guess thats one good thing Dan Hesse did. Anyway I think here in knox we will see 4g lte soon even if its limited at first.
