O2 and Vodafone announced via a tweet, while Three took a bit more effort and actually wrote a press release filled with rearranged sentences from the Google announcement (MIAOW!). No pricing or tariff information id forthcoming however, but interestingly SIM free phone retailer Clove has announced that they are offering an unlocked 16Gb model for £514.80 with stock arriving November 7, 2011.
With availability only a few weeks away, hardcore geeks with a disposable income will be hard pushed not to get hold of one. But the masses might wait a little while as half a grand is a lot of wedge to blow on a phone.
You can pre-order the from Clove here.
