Apple might be readying a show-stealing phone today, but Samsung still has its own premium hardware to compete in the form of the Samsung Galaxy S III. Not only is it heading to EE as a 4G phone, it's also battling back with an array of new colour options too.Once just in white, then in 'pebble blue' (after a problem with production), the phone them appeared online in black, fuelling rumours of new variations coming to market. Now Samsung has unveiled its new range of shades, all apparently inspired by 'the Earth's richest minerals' rather than simply being a way of extending the shelf life and exclusivity of the phone.Those four new colour options have now been confirmed as titanium grey, sapphire black, garnet red and amber brown, aka grey, black, red and brown. It isn't just a matter of heading to your local retailer to get one of the new colours though.The titanium grey S III will be the 4G model, so you'll need to sign up to the EE 4G plan to get that one. If you want the garnet red model, that's only available via Carphone Warehouse.The other two shades (sapphire black and amber brown) should be universal, although they are not landing until 'later this year', probably to boost Christmas sales. If we hear anything more about those, we will let you know.
