I'm so sick of this! I'm sick of carrier contracts and I'm even more sick of not being able to buy a phone that I can't take from one carrier to another (and overseas)! I thought LTE would finally solve this for us. I thought with LTE it would support every carrier and I could finally get an unlocked one, shop around and switch on a whim. Nope! Now I have to choose between a model that will work with Verizon or Sprints LTE or one that works with AT&T. No word on whether the unlocked one for AT&T will work overseas and I presume the one for Verizon/Sprint will NOT work overseas with GSM providers. What about T-Mobile? No idea. **** these carriers! Why doesn't the FTC step in and regulate these guys to all work in an interoperable way? Every other country in the worlds seems to be able to do this, why can't this country get it together? /rant Anyone have any advice or articles with good technical explanation on why this is so, frequency specs, etc?
