T-Mobile G2X has the Nvidia Tegra 2 dual core processor plus compatibility with T-Mobile&39's 4G network.

LG has just announced the T-Mobile G2X, which is the much-awaited U.S. version of the LG Optimus 2X. It appears that T-Mobile and LG are going after a G prefix naming convention with their higher-end devices, the first being the T-Mobile G-Slate tablet.

Like the Optimus 2X, the T-Mobile G2X has very impressive features. It has the coveted 1.0 GHz Nvidia Tegra 2 dual-core processor, a beautiful 4-inch WVGA display, 8GB of internal memory plus the option of up to 32GB with microSD, HDMI mirroring, DLNA support, an accelerometer, a gyro sensor, 1080p MPEG-4/H.264 playback and recording, an 8-megapixel camera on the back, plus a 1.3-megapixel camera on the front. T-Mobile customers will also be glad to know that the G2X handles T-Mobile's flavor of 4G with support for HSPA+ that has theoretical download speeds of up to 14.4 Mbps.

We should note that the G2X ships with Android 2.2 FroYo and not 2.3 Gingerbread, but LG has mentioned it should be upgradable to 2.3 in the future. We don't yet know the price or availability, either, but rest assured that it should be out before the year is over. We'll try to get a closer hands-on impression as soon as we can, but here are a few press photos to tide you over in the meantime.
