[Robin Paulson]

this company are launching a service for cheap roaming deals in
various countries around the world. interestingly they are also
offering voip using available wi-fi connections, similar to the
t-mobile hotspot, for 1.2 use cent a minutes. no word on seamless
hand-off between the two though

they sell a custom sim card which will work in any gsm/wi-fi phone,
presumaby including the neo, and also have a range of cheap gsm/wi-fi
phones

at the gsm rates i will save a heap on phone calls (in NZ), even more
when i get a wi-fi phone
