sorta. It's unlimited as long as you don't make it seem like you're using it to tether to your computer. Ie., as long as you stay under a limit, it's unlimited. hahhahahaeehehee .. er.. yeah.
Verizon has 2 data plans. The $30 is for BIS (personal use)
The higher priced plan (I think it is $45 or $49) is for BES
(corporate use on a BlackBerry Enterprise Server)
Irrespective of which you are on VZW WILL NOT sell you a BB without
one or the other.
As long as your service is unlimited, the browser you use matters not.
that's my point: you're not supposed to tether on VZ's $30 plan. How they can tell is through a limit on the unlimited amount that, if exceeded, creates a (rebuttable?) presumption that you are exceeding the unlimited limit through tethering. See?
