Shawn Blanc:

You can use the mobile hotspot to give internet to up to five computers (or iPads). And while the mobile hotspot is a great feature, on Verizon’s CDMA network you can’t use data and voice simultaneously. If you’re broadcasting an internet connection with your Verizon iPhone and someone gives you a call, then the connection goes dead. Like when you were online using dialup and someone called your house.

Doesn’t sound like fun to me. We can argue all day about the quality of Verizon’s network when compared to AT&T’s, but you can’t argue with this. Cellular data just doesn’t work when your making a call on Verizon’s network.
