So it seems the US version of this phone supports band 26 and 41 (but not 25) that are used by Sprint. Any confirmation that this will help with signal in the US? Or any other info?
Nothing official yet. That would depend on whether Sprint and T-Mobile plan to integrate the networks, since Sprint is using CDMA and T-Mobile is GSM. This is something that might be fleshed out in press releases over time, but no official word that we know of.
