A number of Android tablets have GPS without Cellular.
So why is Apple forcing you to get Cellular if you just want GPS?
Some guesses I have is:
Shared antennas.
Cellular (Qualcomm?) chip includes both functions.
A-GPS (using cellular to quickly download updated satellite data)
or all of the above?
Also a ? about A-GPS,
does one get the satellite data even if you do not subscribe to cellular service???
EDIT:Wiki says "For billing purposes, network providers often count this as a data access", so this suggest it does require subscription, but not conclusive.
