The most expensive version will sell in the $800 range without a plan I'm sure. But that's no different than past versions. If you have a plan, you can still get the same pricing as ever.
I'm going straight for the iPhone this time around. I think it's dimensions are going to be great for phone. I don't want to old a brick to my earlobe. Still trying to decide whether or not I should go with AT&T or Verizon. I know AT&T is supposed to have a similar data share plan as Verizon.
