You can argue yourself blue in the face over it. I suggest you join the "class action" litigation mentioned above.
XM and Sirus do lease space, expend their technology to provide the data which they charge you for, regardless. Verizon provides the data bandwidth by which you would access maps to use your GPS location. Same analogy to me.
I don't really care. But if you have Verizon as your carrier, have you contacted them? As far as these forums are concerned, several members have been banned from membership here over just this issue, because I assume they feel they can seek to vent their anger here. Find a Verizon forum, it could be a more appropriate venue. The BlackBerry is not disabling your GPS, Verizon is.
