I played with some PC apps, and I discovered People app package for ARM. I managed to install it, and suprisingly, it works. Calling, texting, adding new contacts, live tile, so I think, that trully, everything works.
It looks like this.
I managed to make it installable. Download here. It launches, but it's slow and I don't know if it works properly. It says it can't connect to camera, but I have a 1020 so I don't know what about other devices....
