a sprint account executive told me that they are upgrading the antennas, but they aren't throw the fiber optic cables, so i;m think the 1005 will be some time in the summer. i think the PR/VI will be the first market at 100%.
in carolina/trujillo alto (saint just) appear that they're upgrading the antenna, appear in the weekend the 4g but the speedtest was awful, and then just 3g in ehrpd.
is like the One x of aT&T, they announce upadtes diferently of the international version. for example, the international version runandroid 4.1and the att runs 4.0, but the evo runs 4.1
