Is the touch just wi fi enabled which would mean that you need to be able to access a wireless network (such as if you had a wireless network at home or where she works, or somewhere else, and has access to it by the admin of the wireless network) like WIFI on a laptop. If it is then you wont be able to access the internet unless your in a wi fi (and have permission) area.

The Iphone one the other hand I think just uses its GRPS or 3G netowork to access if theres no WIFI (or its not connected to a prefered one), which you then would pay the mobile provider, but you can use it pretty much anywhere you can get a signal.
