T-Mobile has announced a new Android phone, the T-Mobile G2x, writes Mashable's Stan Schroeder. It's a modified version of the LG Optimus 2X, considered to be one of the most powerful Android devices on the market today.

The T-Mobile G2x offers a dual-core 1 Ghz Tegra chip, a 4-inch WVGA screen, 8 GB of memory (expandable up to 32 GB via microSD memory cards), a 1,500 mAh battery, an eight-megapixel rear camera with 1080p recording capabilities and a 1.3-megapixel front camera for video calls. It also features HDMI, accelerometer, a gyro sensor, and a micro-USB port. The device is currently running Android 2.2, though it will be upgradeable to 2.3 at a later date.

Though the suggested retail price for the T-Mobile G2x is $499.99, consumers can ultimately pay $199.99 for it after both an instant discount and a mail-in rebate, as long as they are willing to sign a two-year contract.

So what are consumers getting for their two hundred bucks? A lot, according to the website Android Community, which calls the phone “oh so sweet to behold.” Writes blogger Chris Burns, “Inside you’re going to find a Vanilla version of Android 2.2 Froyo (that meaning no mods from T-Mobile, just pure Googly goodness,) on the outside you’re going to find front and back facing cameras including a fat 8 megapixel on the back – and smoothness. Simple designs breed simply awesome experiences, if I do say so myself.”

The Android Community Web site also features a host of photos and screen captures from the phone, for those tempted to be early purchasers. The T-Mobile G2x is currently available online online. It will be available in store on April 20.
