ArcGIS is an application from ESRI, made for the iPhone. It sports a fantastic looking interface, and maps are pretty quick to load up. And there are a pile of different map views you can shoose from – including various topographic maps, satellite views, hybrid maps, and more. There’s even a Canada 1:20K Basemap.

ESRI has also built an online application that lets you create your own custom map views

And it’s free!
