Yes, the sim will work if cut and sanded. No, AT&T will not like it and your service will eventually be cut.
I understand AT&T's stand regarding unlimited but why would they care if you have a 3gb data plan for the iPad and use it instead on an iPhone?
They don't care.
ritterson and other fanboys are just making **** up to scare people. You get used to seeing that sort of mentality around grey areas which use exploits that aren't technically illegal, or even against TOS.
After you note that plenty of people, including myself, have been doing this since back BEFORE the unlimited data plan disappeared, you'll realized that it's totally legit.
Most of the time, at&t employees give me the reaction, "Damn, which I could do that.", "Neat!", or some similar prose. The rest just blank stare and say, "uhm, ok."
