Vodafone UK have updated their website to include the Google Nexus One availability. The phone is up for pre-order at the moment for an April 30 launch although deliveries are not shipping till May 5.
The Google [GOOG] phone has been available in the US for a while now. It runs a 1GHz Snapdragon processor from Qualcomm, has a 3.7 inch touchscreen and a number of features that make it one of the flagship Android devices available.
Regarding prices, they are quite good for us in the UK where you can actually pre-order on the Vodafone website rather than through google.com/phone. The phone it's self is free on 24 month tariffs for £35/month. If you opt for an 18 month tariff you can still pick up a free Google Nexus One for £40/month. Full prices available here.
Right now there are no other price plans for the phone out of the 18/24 month contracts. Also there is no option at Google.com/phone to pick one up SIM free as they direct you to the Vodafone site to pick up a contract.
We'll keep our eye on the Vodafone prices and availability and let you know if any changes happen.
