Yep, and it doesn?t have to be 4G either, 3G is fine.
I prefer maps.google myself, mainly for the street view which can be handy at times for seeing where you will try parking etc before you get directed to where you want to go, but also because they respond very quickly to reported map errors quite a bit of the time. Apple basically just ignores all I have reported.
Their users generally do love them but IMO a decent smartphone leaves them for dead now.
The other big advantage with a smartphone is that you can just tap on an address in an email etc and auto get directions to there in the mapper with the best of them.
You don?t have to have coverage with the best of the smartphone apps, they will load the maps into the phone when you do have coverage or wifi and use that when navigating. Completely auto with maps google.
And maps google does a hell of a job with unusual congestion in countries which all google to use the cellphone tower data to actually measure traffic movement speeds in real time. Nothing else comes even close.
