hey, I'm having issues getting this thing to work... have ArcGIS 9.3.1 and Iphone 4 loaded with the arcgis app. I have uploaded files via my global account- all good.... but can only see folders on the iphone, not there contents.
The ArcGIS app can access the published services and not file, mxd or lyr. Publish your mxd as service, create a web map on ArcGIS.com with that service and access in the ArcGIS application.
