Instinct does not allow you to use it as a modem in case you want to tether your laptop while on a trip. No way to disable the secondary modem NAI. For all that we pay for "Unlimited Data Access", we should be able to use it as a modem occasionally.
Actually, if you look at the fine print in dark gray on black at the bottom of the page, you will see "Services are not available for use as a modem" for the Simply Everything Plans... http://www.sprint.com/everything

It's not just the Instinct that has one of it's built-in features forbidden, it appears to be any handset on a simply everything plan.
You cannot get to the hidden menu from Settings > Display in order to see if there is a NAI setting. No way to enter 0 to see hidden menu. Some people taking Instinct back because of this & other problems. Check out sprintusers.com and howardforums.com
I was going to buy iPhone 3G but it doesn't have Phone As a Modem. So I bought 2 Sprint Instinct phones yesterday with $129.99 family share plan. I only used my old phone maybe once or twice as a modem when broadband was down (I don't download music/movies anyways). But today when I tried to use Bluetooth on Sprint Instinct as a modem, it connected but then gave an error. So looks like Phone As a Modem is disabled. If After paying $129.99 + Tax to sprint, I can't use Phone as a modem occasionally (when broadband is down), there is no need to keep Instinct over iPhone. I am going to buy iPhone 3G as soon as they are released and return Sprint Instinct's under 30-day return policy! Anyone else feel the same way?
u so can use it has phone has modem the firmware needs to be twkked a little

To get your MSL number, just dial *2 and go to the tech support option "all other problems" and tell the operator you need the MSL number for this phone. Each phone has a unique MSL number. Some operators will give you the number, and some won't. If they are being nuts about it, just hang up and call again to get a different tech support person. Most will happily give you the number so you can do all the wonderful reprogamming things to your phone. Google it.
