Many thanks, working great on my device: registered in 7 seconds.
Bug report: in the contact list I see duplicated name that are contacts with multiple numbers defined.
I think you'll redesign that window because there's not even the possibility to search a contact but the problem I'm reporting is that if I have a contact with two mobile numbers and a non mobile number I see the contact three times (it should be visible just two times, I think).

UPDATE: I see only non mobile numbers with the internetional code (+39 for Italy)
