I've also included the java code to (SAX-)parse through the XML based on country code and mobile provider code, and if that fails, gather all access points for that country (see java-attachment, GetApnStringsFromXml method).

We're going to need multiple MNCs for each operator, since for example
here in the US (via acquisition, since T-Mobile USA was put together
from a few different providers over about 5 years) they have 160, 200,
210, 220, 230, 240, 250, 260, 270, etc.  And Cingular/AT&T has quite a
large number of MNCs too since they are the product of a lot of mergers
and acquisitions.

So as long as we can have multiple <mnc> for each provider, and multiple
<mcc> entries for each country (US is 310 and 311 and maybe more), it
should provide for the configs I know about.
