Hacking Cell Phones

Most people know about that nice little menu on Nokia cellies, the
*3001#12345# menu. You have access to cool menus, the setup of the phone, and the coolest, the field test. That without a doubt in my
mind is one of the coolest things I have seen on a cell. Sure, those
bars on the side of the LCD are useful, but i want to know the exact
Db level. Anyways, go up to NAM 1. Theres a bunch of lists there,
which I wouldn't recommend fuckin' with. Going down further, you see
something called P/RSID lists. Open it up, and go down to alpha tag.
Entering stuff in this tag will allow you to put text on the front
of the phone! Of course, you have to enter in the info for your
provider in the other spaces provided, but that won't take too long.
On some companies, this won't work, so tough luck if it doesn't.

Security (or lack there of)

Go find a friend's phone. Is it "locked"? Not any more. Go back to
the *3001 menu, which is accessible even if the phone is locked, and
go to the security menu. Using the number provided, you can get into
the phone. Simple enough.

Call Forwarding

First I must give props to Vicious for giving me the idea.
Call forwarding, if your brain dead, allows you to forward your cell
number to any other number you want, well, at least I would believe
so. The code for forwarding can be found from the friendly operator,
or even in some spam the company sent ya trying to hype new services
you don't need. There are two types of forwarding, call waiting and
constant. Call waiting only forwards when you your on the phone, so
you can send it to a vmail box, and constant is self-explainatiory.
So, why not get two phones, and call forward them two each other! I
have tried this, with interesting results. If you call forward two
cells on the same provider, the cell site figures this out and the
call is stopped almost immideately. But, if you use two different
providers, then it will last forever in a loop. Granted, the call
won't go anywhere, and I didn't hear anything cool when I did it,
but still fun.

So go out there and have some fun with one of the most useful and
annoying devices on this planet!

PS: If the phone is locked out, or you haven't been paying the bills,
then the only two numbers to dial are 911 and *611. *611 is tech
support, so it might be different for you. And props to Tripp for
