T-Mobile users have the option of buying Galaxy S3, but having an option to buy the One X too would be welcome. And it seems like HTC is liking the Samsung’s all-carrier-release policy and is taking it to heart, too — as they plan to release the One X on T-Mobile too. Btw, HTC already available the One X on AT&T with 1.5 GHz S4 dual-core processor inside, but looks like the T-Mobile One X will pack in even higher specifications, going by the + sign that it’s been rumored with, which might mean presence of Tegra 3+ processor.

We already know that a successor to Nvidia’s quad-core Tegra 3 processor would be Tegra 3+, one with higher clock rates and compatibility with 4G LTE and higher HSPA+ speeds. So, if the rumor turns out true, T-Mobile One X might become the first device to launch with Tegra 3+ processor, maybe featuring 1.7GHz quad-core processor. The rest of spec-sheet should be same as that of AT&T One X and international One X, including RAM of 1 GB.

The T-Mobile One X is also knows as HTC Era 42, btw. Any more details on T-Mobile One X are not available for now, so we gotta wait for release date, exact (official) specifications, etc.
