A brief note to fellow expats

If you value your ability to look up directions routed on public
transit on your iPhone, do not allow your phone to upgrade itself to
iOS 6! Apple ditched Google Maps in the Map app for their own
substandard mapping solution, and it doesn't include train and bus
routes. Kind of important info outside the US...

Keep an eye out for a new map app direct from Google. At that point
you can upgrade without fear of lost utility.
