Up until this point, if you wanted to get the 3G version of the Nexus 7 in the US, it appeared that AT&T was the only option. Now, however, Google has provided a T-Mobile version on the Play Store. This model comes pre-loaded with a T-Mo SIM. According to the tech specs, though, they're functionally identical. This will just save you the trouble if you prefer magenta over blue and orange, I suppose.
Back at the announcement of the Galaxy S III, many people were quick to note that Samsung disclaimed the availability of the Exynos quad-core processor powering the beast as contingent on certain issues of geography. And then we learned that, for reals, the US versions of the Galaxy S III would be shipping with Snapdragon S4 dual-cores onboard - the MSM8960 chipset, to be precise.
And that included T-Mobile's version, which many speculated (myself included) might be the only Exynos-packing Galaxy S III to make its way to the US of A.
