Swiss website PocketPC.ch has posted this video of a developer handset of WP7, demonstrating what it can do while on a call. The whole thing is in German, so you’ll have to base your knowledge on what’s immediately obvious.
He demonstrates answering a call, switching out of the dialer, mute, speakerphone, hold, and call forwarding. At least, that’s what I can gather.
Any of our readers fluent in German, and want to weigh in on the video, and what he says? Anything super cool that he mentions that we might have missed in our monolinguistic viewing?
