A couple of things… it's definitely true that the "unlimited" regular data plan is capped at 5GB. They say unlimited, but it seems that basically, all of the cell phone guys have got together and decided that 5GB is damn near impossible to use on any smart phone unless you're doing something explicitly forbidden… like running a web sever, or say, tethering. This isn't actually true… try watching YouTube in HD for 6 or so hours, and you'll blow that cap (assuming the YouTube app actually accepts an HD stream). Or if that won't do it, try 80-something hours of high quality streaming audio.

In your "MyVerizon", they say unlimited, but when you sign up, there's an "Unlimited (5GB)". But you read the actual agreement, it says "Anyone using more than 5 GB per line in a given month is presumed to be using the service in a manner prohibited above, and we reserve the right to immediately terminate the service of any such person without notice. We also reserve the right to terminate service upon expiration of Customer Agreement term."

When you get a tethering agreement, it'll be treated the same as a "Wireless Broadband" plan… a very up-front, well stated 5GB per month limit. This is a change… I had this service some years back, and there was no open limit. They still had a limit… just didn't tell you about it. If you used too much data, they just send you a "Dear John" letter, kicking you off the system (more like 10GB, based on those I met in forums who had been cut off). But hey, if you ever need to get out of your contract without paying it off… but check if they have overage fees

The uncomfortable part of this is that it sounds like they're offering 5GB for tethering and 5GB for normal use, not simply a pool of 10GB that, oh-by-the-way, allows tethering.This suggests there's going to be a tethering server or some-such to meter the tethering activity. Which is a shame… openly allowing this could yield some cool apps… make your DROID a wireless access point, for example (of course, you could tether your DROID to one PC and use something like "Connectify" to build the access point, at least if you have Windows 7). A great deal over a MiFi if you don't need it every day.

I am currently paying for two plans with Sprint. One for my HTC Hero and one for my MiFi. It would be nice if I could tether my Hero and not have to carry and use that second device (the MiFi).

Plus having two plans gives me more allowance toward transfer.

Sure some people my exceed the "unlimited" threshold enough to warrant response from vzw, but 99% would not… so 2 plans = FAIL. I am using my phones internet, shouldn't matter if the phone or a PC is using it. Same speed, same service. This lame fee is just another pure profit charge just like text… Won't people just learn.

Can you use the second data plan for the 2nd phone on your plan… probably not.
