iPhone 4S Rival Alert : Sony Ericsson Xperia Arc HD Nozomi Appears

The first HD smartphone from Sony Ericsson (soon to become Sony) has appeared in glorious full definition on GSM Arena thanks to an anonymous tipster.

The handset, which will almost certainly be called the Xperia Arc HD (codenamed Nozomi) features a massive 4.3-inch 1280x720 pixel capacitive touchscreen display (with the same pixel density as the iPhone 4/4S), a dual core Qualcomm Snapdragon S4 chipset clocked at 1.5GHz (with the Adreno 220 GPU), at least 1GB RAM, microSIM slot (like the Nokia N9 and the iPhone 4/4S), 16GB or 32GB onboard storage (though no microSD port sadly), a 12 megapixel camera with full HD video recording, an HDMI port and a non-removable battery.

Expect the beast to come with Android 2.3.5 Gingerbread with an update to Ice Cream Sandwich a certainty.

Sony Ericsson is certainly fond of big screen smartphones; in 2010, it released the Xperia X10 which had a 4.3-inch display and this year a few large screen smartphones like the Xperia Arc.

Expect the Xperia Arc HD to be presented at CES 2012 next year with a full blown release at Mobile World Congress towards the end of February 2012.
