An APN is similar to a URL on the WWW, it is what the unit makes a GPRS / UMTS call. The
service provider is able to attach anything to an APN to create a data connection, requirements for
APNs varies between different service providers. Most service providers have an internet portal
which they use to connect to a DHCP Server, thus giving you access to the internet i.e. some 3G
