Okay, do you know about the secret menu on your phone?
When its flipped open and in the menu select screen hit 0.
A password thing should come up, the password is all 0s.
You will see different menu options.
One is WAP settings, if you play around with that you will notice the menus are not editable.
Note: I would highly suggest you not mess with too much in those menus, you could mess up your phone.
Well to get free internet you have to edit the wap settings, here is a tutorial for your phone to edit those settings.
This is the one that I used, it works. I suggest you follow
exactly what it says, or you could mess your phone up.
