Let the retail cell phone pricing wars continue. The recently announced T-Mobile HTC G2 isn't even for sale yet at the carrier, but Radio Shack announced via Twitter that it is slashing the price of the device to $149.99 with an instant rebate and two-year agreement.

Best Buy last week made the G2 available for pre-order beginning on Sept. 10 and will launch the device in its stores on Oct. 6 for $199 with a two-year contract.

T-Mobile also hasn't yet released pricing information for the new HTC device, which is the first Android smartphone phone to run on T-Mobile's HSPA+ network, but various published reports indicate that the carrier might price the device at $199, after a $50 or $100 mail-in rebate and two-year contract. It will be available for preorder at T-Mobile later this month to existing customers, the carrier said.

The G2 -- which T-Mobile says is the successor to its G1 Android device -- runs on Android 2.2 and has a 3.7-inch touchscreen display that rotates and a hinge design that opens to a sliding full QWERTY keyboard. It has a MSM7230 Snapdragon processor running at 800 MHz and features seven customizable home-screen panels including one that clicks to Google applications such as Android Market.

The device also offers the new Google Search feature Voice Actions, which lets users make voice-activated calls and use voice commands for sending messages and web browsing. Users can also create a new account right from the home screen.

The G2 also comes preloaded with other Google services including Google Search, Gmail, Google Maps, and Google Earth. It has a high-definition video camera and 5-megapixel camera with LED flash and autofocus. The device offers a preinstalled 8GB microSD memory card and support for up to 32 GB, as well as enhanced web browsing features such as Adobe FlashPlayer and pinch and zoom functionality.
