AT&T Breaks The Apple SIM’s Best Feature, Locks It Down If You Pick AT&T

The idea behind the Apple SIM that comes in the new iPads is most excellent: one SIM, many carriers. Whenever you want to switch carriers, you’d just pop into settings and pick the new one. If you want to bring your own SIM, you can — but otherwise, everything happens through software. No swapping SIMs, no ordering new SIMs, no hassle.
