I think the address book isn't the issue I think what Luca is suggesting is a multi-imsi sim, not just a roaming sim So it has his home IMSI as a primary and a virtual IMSI pushed when he lands somewhere new Heard someone was working on that Not one or four countries, all of them Now what was the companies name again :-) (the phone book is already there as his numbers are in international format) plus of course, sync with my friends in Funambol
Luca Filigheddu The solution that is closer to my idea is the one recently launched by Funambol and Jajah, but it works in Italy only and it makes sense for italians calling abroad very often. What you say about the virtual IMSI is the right answer.
