Having used my iPhone to tether via PDAnet for well over a year I can say no chance I'll waste $130 on the 3g radio or the 3g data I'm already paying for on my iPhone.
Nothing better than a BT or Wifi adhoc tether setup. iPhone remains in your pocket and you have a nice PW protected hot spot walking around with you. It's no different than using one of the MiFi devices all the carriers want you to pay $60 per month for, screw that.
In nearly 15 or 16 months of having my iPhone avail to tether to my MBP, the heavies use was March 09 to stream Slingbox to my MBP to watch the NCAA tourney. I think i used somewhere just shy of 5gigs. Not a word from ATT. Average use was less then 200mb a month otherwise.
