GPS without cell phone service?

[mruser01]

Hi,
1. Does the iPhone have a tradition GPS chip? I understand that iPhone uses A-GPS for faster lock. But is there a GPS chip inside?

2. I would like to use the iPhone a cell phone service for GPS service only (perhaps some offline maps if available). Is this possible?

Thanks.

The only offline maps I've seen are the car navigation ones which don't require a cell service to operate. But otherwise Google Maps requires an active connection. And other maps like Mapquest also requires an active connection.

As for a traditional gps.. not sure but I would guess that if it does or doesn't it still requires an active connection for it to bring up the maps. I know that after it finds your exact location it follows you around like a standard gps unit does.
