Q: apple SIM and AT&T
IF I sign up for an AT&T plan using my Apple SIM, can I later cancel that AT&T plan and sign up with another Apple SIM carrier? Or is my apple SIM forever dedicated to AT&T?
MacBook Pro, Mac OS X (10.6.8)

When you attempt to set up service with an Apple SIM and AT&T yes, from that point on that SIM will only work with AT&T as the setup message will warn you of before you commit. Various tech news sites have also confirmed that AT&T is locking the SIM. However your hardware is not locked to anything, but you will need another Appl SIM or carrier SIM to switch to another carrier.
