Version 0.0.1-3 is send to extras-devel.

A short explanation on the latest change:
Choosing "Current cellular info" will show extra information if an internet connection is present. It will search and display the geographic coordinates of the celltower found on opencellid.org. These coordinates are then used to find and display the postal location of the celltower (using maps.googleapis.com data). The info should be updated if the cellid changes.

I don't know how thorough the opencellid.org databases is, but it is way to big to store locally on the phone
