Many/most GSM/GPRS/etc operators will have multiple APN's - one which is
setup for NAT, and the other which gives a public IP address.
By default, most "dumb" phones will use the former. Data cards will use the
latter, and smartphones seem to be split between the two - although
obviously it will vary between providers.
