Which spectrum are they going to share? I know T-mobile has some PCS spectrum that could surely help Sprint. I believe some of it is even adjacent to the Sprint G-Block that Sprint is rolling out a 5x5 LTE carrier on right now. I guess it would be pretty sweet if they combined forces, and that 5x5 LTE carrier was increased to 10x10 or more, or multiple PCS LTE carriers were introduced. T-Mobile is free to partner with Clearwire all they want, separate from Sprint.
