APN enable/disable

If you have multiple APN configurations that support internet data (that is, with an APN type including "default" or the catch-all "*") this allows you to choose which one of these is currently enabled.

If you only have one APN configuration that supports internet data, or if this isn't one of them, this field will probably be disabled and would not make sense anyway.

Checking this box is equivalent to selecting an APN configuration from the menu in the "APNs" screen.
