John Gruber elaborates some more about how the iPhone could know your position in order to suggest local seafood restaurants. Secret GPS? Cellphone tower triangulation?

Well, I’ve got an idea for a technology that would work — I know it’s a bit of a pie in the sky, but blogs are the realm of speculation: How about having the maps application fucking remember what’s the last map you viewed (and possibly a couple more in the history)? Yeah, it’s that complicated.

I can’t really fault Gruber for overlooking the option, though: no online maps application that I know does it. Close Google Maps and reopen it, you’re back to the big U.S.A. map (hello, I’m in France!).
