On krillin rc-proposed 135, I confirm the error if I go the the website
in the description, with location detection using cell-data only.
However in HERE I get a fix quickly but very inaccurate (20km away from
my actual location, in the middle of the sea)

Title:
  Ubuntu Phone is not getting a mobile network cell triangulation
  position

Status in Canonical System Image:
  Confirmed
Status in location-service package in Ubuntu:
  Confirmed

Bug description:
  Hi!

  I think that the mobile network cell triangulation position is not
  working in Ubuntu Phone OS.

  The position should be really fast (~1 - 5") and I'm thinking that
  Ubuntu Phone is waiting for a real GPS position every time.

  A good test could be this:
  - Go to a room, way out of a sky for avoid a real GPS signal.
  - Set WIFI service OFF.
  - Set GPS service ON.
  - Set data connection ON.
  - Go to this web into the phone: http://leafletjs.com/examples/mobile-example.html The web will ask you to allow access location.
  - It's really important not to have a GPS position cached too.

  In a PC or *any* Android you'll see your position immediately.
  Bug: In Ubuntu Phone an error will appears. This error is because the geoposition (https://developer.mozilla.org/en-US/docs/Web/API/Geolocation/Using_geolocation) is not working with the cell triangulation network data.

  You can try a lot of apps like Google Maps, OSMTouch, HERE map, uNAV... and a fast position from data connection is not happening, unless you be with a WIFI connection.
  If you try Google Maps in Android, the position will be really fast just with data connection.

  Thanks in advance!
