I often travel internationally (with no data roaming) and I've noticed that the iPhone's A-GPS is incapable of determining my location when I arrive in a new place, even if I've pre-loaded my route/maps in the maps application prior to arrival. But once I've connected to the internet - even for a few seconds - my phone is permanently able to track itself in that city, even after I've left and returned months later.
It's going to be unfortunate when I can't do this anymore because of people blowing this issue out of proportion. I hope Apple will at least provide the option of caching this data for longer than 7 days.
