The upcoming Sony Xperia S in white will be exclusive to Phones4U at release. Which means that the networks are only going to be getting the black model at first. O2 Orange and Three have all mentioned they will be stocking the Xperia S.
Phones4U have set up a pre-register page here for you to give them your details to be contacted when it’s available. No mention of prices yet. No mention of dates yet. In fact the pre-register page doesn’t even mention the colour.
I really like the idea of this. Especially in white. It’s just the thought of what Sony have done to the nice new ICS software that makes me shudder.
