All iPads: AT&T Unlimited Data Plan Owners with iPad 3 & Mini - SIM Swap?

[sdsvtdriver]

Those of you with iPad unlimited data plans --

Are you able to simply swap SIMS between your iPad 3 and iPad mini? If so, has AT&T screamed at you yet?

I'm deciding which mini to get and I already have an iPad 3 w/UNL data. I'd prefer to swap the SIM from one device to the other when needed, but AT&T has generally been resistant to permitting that in the past. A wifi iPad mini seems rather useless as the benefit to me would be mobility since I have the iPad 3 at home already.

Thanks
