scuwp: ... A big value with iOS is having the 'find my iPhone' app which we all regularly use. ...
Sorry, just to clarify, are you talking about
- Find iPhone (with green radar icon) for locating devices?
- Find Friends (orange icon with two white figures) to locate persons?
'Find iPhone' give you the option to not only locate the device, but also ring the device, lock it and optionally erase it. Once enabled, this is always on.
'Find Friends' on the other hand is to notify you of the location of people and optionally notify you when they are in the vicinity of a specific location. This location sharing can be enabled for a limited time of indefinitely.
