Allow me to clarify, there is a difference between Unlimited PDA/Smartphone or Blackberry versus Unlimited Aircard usage where you would be using a laptop.  Unlimited DOES exist using the PDA/Smartphone plans of $29.99 Consumer or $44.99 for the Enterprise addition.  You add the Data Plan Feature to your PDA/BB/Smartphone and you CAN use data what would be refered to as UNLIMITED... However, you cannot then use that same plan to tether your Smartphone/PDA/BB to a Laptop...  I hope this makes sense, if you are still confused, I have some great collateral that explains it and I'll get it to you, just send me a Private Message..
