Nice trolling
The file in question is a cache of location assistance data *received* and used to speed up the time required to determine your location when using maps and other location services.
The file in question is a sqllite database which had a default size of 2MB, this sounds small but it turned out to be too big for the data in question. This has been reduced in size. It is also not backed up now.
iOS sends information about cell masts and WIFI hotspots to assist Apple in building their own alternative to SkyHook. This data is anonymised.
Google sends the same data but a unique identifier is present on it. So if anyone needs to get their shit together it is Google.
But I'm sure Google are analysing and selling this data on, it could be useful to mobile operators to see where people are most of the time and where they need mobile coverage.
