So it looks like I'll indeed be back in 'town' in August (provided things go well tomorrow) and I'm trying to decide if I should pick up a GPS unit while back in Canada or buy a phone through one of the companies JPN-side. I understand that I can buy a map upgrade from Garmin that will have many maps of the main cities of Japan, but I've also come to understand that many of the other phones now available trough KDDI AU, DoCoMo and SoftBank will come with an integrated GPS system would would certainly be invaluable.
Does anyone out there know if most of the phones released these days do indeed have usable GPS?
