Rumours of a Zune phone announcement (and denials) abound. You can even see pictures of it on the internet. Fortunately I have learned, thanks to Jon Holmes and "The Now Show", that sometimes things on the internet aren't true (quote: "1 in 4 potatoes is a rabbit's egg").
Here's my own personal Zune phone wot I made which I'm finding to be quite functional though the lack of a touch screen makes operating the keys somewhat difficult.
Anyway, it will never displace the Samsung Omnia in my affections (which is now running Route 66 and makes a cracking SatNav). I love my Omnia.
