Contract prices are still a little vague, but if you want a Nokia Lumia 800 on pay-as-you-go, the Three network has come forward with a price for that. At least, one has been spotted online.The Windows Phone 7.5 (Mango) handset will cost £399 when it hits the shelves. That's according to Recombu, which did a bit of digging at Nokia's official site. Try and order one on pay-as-you-go via Vodafone or Orange and you'll get nothing. Tick the box for Three and you'll get the price, as well as the call rates to both landlines and mobiles (26p for both per minute, if you are interested). Follow the link and you'll be taken to Three's landing page. Job done.Sadly, you can't grab one yet with the launch date still a little vague. November is being talked about, the the official word is 'coming soon'. Still, at least there is actually a non-contract option. Initially, Carphone Warehouse had confirmed the handset for £449, but later said the device would be contract only. That no longer seems the case. If you prefer a contract deal, Three, Vodafone and Orange should all be able to oblige in the coming weeks, probably for around £36 per month if you want to put us on the spot.As for the handset itself, that launched last week, with both Nokia and Microsoft hoping its mix of good looks and impressive functionality will give both companies a much-needed boost in the high-end smartphone market.
