The Sony Ericsson Xperia Arc HD has turned up ahead of an official announcement at CES getting papped in the process.

The phone, which has turned up on ITProPortal, just shows the phone will keep to its HD name offering a HD screen resolution as well as letting users snap and video in HD thanks to a 12-megapixel camera around the back.

The Sony Ericsson phone "obtained from a trusted source" will, according to the site, run Gingerbread 2.3.7 rather than Android 4.0 Ice Cream Sandwich and come with a Qualcomm 1.5GHz processor with 1GB of RAM and 8GB of storage.

The fact that it is running Gingerbread rather than Ice Cream Sandwich goes against Sony Ericsson's promise made in 2011 that all new phones would include the latest Google operating system.

The Xperia HD, as the site calls it, won't have a microSD card slot. Sony Ericsson has also opted for a micro SIM as found in the Apple iPhone, Nokia Lumia 800, and Motorola Razr suggesting the smaller SIM card format is gaining popularity amongst manufacturers at last.
