If your favoured network is Vodafone and you fancy trying out a Windows Phone 8 handset, tomorrow could be a big day.That's the day Vodafone starts selling Windows Phone 8 for the first time, a few months after the big WP8 launch. Better late than never I guess. The phones in question are the Nokia Lumia 920, Nokia Lumia 820, Nokia Lumia 620, Windows Phone 8X by HTC, plus HTC's Windows Phone 8S.Fair to say that it covers pretty much all price points available for the operating system. What we don't know is the exact pricing of those phones on Vodafone, as they don't seem to be listed on the site as yet.But we don't expect pricing to be much different to the other networks selling the phones currently. So (to give you an idea) the Nokia Lumia 920 is likely to be yours for free for around the £40 mark, with the Lumia 820 nearer the £30 mark.You'll find out for sure (hopefully) from tomorrow, either via the Vodafone site or by nipping into one of its stores.
