iPhone 4S Rival Alert : LG Nitro HD Debuts On AT&T

US-based mobile phone operator AT&T has launched the LG Nitro HD, an Android handset that comes with 4G LTE capabilities.

It will be available through online stores and on AT&T's website from Sunday 4th December for $250 on a two year contract, and will replace the LG Optimus 3D as the top of the range LG smartphone.

The phone - which is also known as the Optimus LTE and was announced last year in Korea - features a 4.5-inch HD ready AH-UIPS display, which has a 326ppi pixel density, the same as Apple's Retina Display.

The screen is said to offer "unrivalled color accuracy, brightness, battery efficiency, and performance", with 500 nit luminance on offer.

Other features include a dual-core Qualcomm Snapdragon chipset clocked at 1.5GHz (the Optimus 3D used a TI OMAP4 and the Optimus 2X, a Tegra 2 chipset), 1GB RAM, an eight megapixel camera, a 16GB microSD card (plus 4GB internal storage), Wi-Fi direct, DLNA compatibility and Android 2.3.5 Gingerbread.

No news as to whether LG will be sending the Nitro HD to the UK (or Europe) or at what price. Other similar handsets include the HTC Sensation XL, the Samsung Galaxy Note and the Motorola Razr.
