The very first time we laid hands on a Verizon iPhone 4, it took us about 0.00000004 seconds to fire up the Settings app and dig into the Personal Hotspot feature. How's that for speed? Can you hear me now, and so on?
The good news: Personal Hotspot works really well, and a monkey with an ice-cream headache could have it set up in seconds.
The bad news: It requires an extra $20/month charge, on top of your (required) voice and data plans, and (optional) texting. And AT&T users don't have it yet.
