is a version of the previously announced 1GHz dual-core LG Optimus 2X, billed as the world's first phone to capture, store and play back video in full 1080p/24 fps resolution. The G2x features what the carrier calls a "Google experience" and comes with Android 2.2 OS, dual-core 1GHz Nvidia Tegra 2 processor, 4-inch 400 by 800 capacitive touchscreen, 8-megapixel camera/camcorder, front-facing 1.3-megapixel camera for video chat, HDMI output with HDMI mirroring, Wi-Fi 802.11b/g/n, MicroUSB 2.0 and a MicroSDHC card slot supporting 32GB cards.
, like its Sidekick predecessors, is designed particularly for messaging and web browsing but adds all the capabilities of the Android 2.2 smartphone OS and Samsung's 1GHz Cortex A8 Hummingbird processor.
For the first time, a Sidekick phone gets the Android OS and a touchscreen, which faces up like a typical smartphone's touchscreen to enable users to dial and access apps. The touchscreen also pops up at an angle via a pop-tilt hinge to reveal a five-row QWERTY keyboard, which was available on the previous Sidekick. When the screen is popped open, it faces the user at an angle, creating a laptop-like appearance.
Another new feature is a VGA front-facing camera and pre-installed Qik Video Chat capability.
