Personnally, I would (try to) add a GPS entry here as it's one of the
main hardware innovation of modern "phones".

 - GPS: location available/not available, trigger acquisition, get last
known location, (...?)

Apart from this (purely personal) subject, the following aspects are
probably expected too in a working phone:

 - "Energy" state/requirements: power-line available, on battery, on low
battery, low-energy target (for user-requested long duration)...
 - (Data) Network availability (zero-cost/cheap/expensive)

Lalo recommended looking at the existing Telepathy APIs. Any more
precise pointers available? (Especially for the last point.)
