Question for those who've installed iOS 8 or read up on it.

There is an Instant Hotspot feature. As I understand it, iOS 8 can connect your Mac to your iPhone via peer-to-peer (adhoc) WiFi and use your iPhone's cellular data connection to provide Internet connectivity to your Mac. My question is, does this require you to activate the hotspot feature with your cellular carrier? That costs an additional $25 or so w/ ATT. If not, I can dump my Verizon MiFi and just rely on my iPhone to get internet on the MacBook on the rare occasions when my MacBook doesn't see WiFi. I have an unlimited data plan for the iPhone w/ ATT.
