After lots of reports of broken GPS and other issues recently, I decided
to write a script that cleaned up the APN list. The script did the
following:
1. Eliminated duplicates. Each APN was given the unique key of
"mcc:mnc:apn:type" and placed into a hash using this key.
2. Removed any APNs where any of these four fields were not set.
3. Set an empty APN type to "default,supl,mms".
4. Sorted by MCC, MNC
5. Merged in the official APN list from FRF91.
