basically the phone uses two different addresses when you use different connections:
3G - "yournumber@vzw3g.com"
hotspot - "yournumber@dun-vzw3g.com"
Hotspot uses the same authorization address as the aircards use, which is a DUN username.
Remove dun from the username and make it the same as the user name on the 3G username and voila, FREE hotspot!
to access EPST here's the tutorial, if you have a Droid Incredible, or EVO you can try it out.
---------------------------------------------------------------------------------------
##778 - hit call/send
a popup will show up: click "edit mode"
PASSWORD: 000000
Access: M.IP Default Profile
Click: DUN NAI
remove DUN from your user name (it should look like an email address when you remove dun, make sure there are NO spaces (ie: @vzw3g.com)
(basically make sure it looks exactly like this "yournumber@vzw3g.com"
YOURNUMBER is what your phone number would be in the address
Once your done, click OK
HIT MENU (capacitive button) click: COMMIT MODIFICATIONS
-----------------------------------------------------------------
It will ask to reboot (not always)
Then voila, FREE hotspot and Tethering
Your welcome
Now, isn't that more painless than having to root if thats all your gonna use ROOT for until a good custom rom arrives?
THIS WILL ONLY WORK ON HTC PHONES, THE SAME METHOD CANNOT BE USED ON MOTOROLA OR OTHER BRANDS!!!
