If you watched the demos of WP7 you’ll notice that they always skip over the two things that make a phone a phone. The dialer and sending texts. That’s cause they’re not completed yet. The dialer is particularly not completed. PocketNow was able to dig up an image of the dialer in its current state. And here’s an image from a video walk through from pda.pl showing the text message screen.
OK so the phone part isn’t there yet, but the Zune part is still sweet:)
