Hi Pierluigi,
you'll first have to reproject your vector map into the lonlat, i.e. a 
geographic projection. Then you can upload the long lat values to your 
vector table. You'll first have to add two fields to your table 
(v.db.addcol). You can then reproject it back to your original 
location/projection or just swap the database file over if you are using 
Hope that helps,
