One thing that I find WP version lacking is to directly send message to a new number.
I need to add the new number into phonebook first and then wait for it to appear in whatsapp.

Is everyone the same? Or do I miss something?

I see. it was a while back when i used whatsapp on bluestack last time before i get a smartphone. I find that is more convenient especially when u just want to whatsapp some sellers on some info.
