How to Unlock an iPhone

Here is a short seven step tutorial for unlocking an iPhone. Once unlocked, the iPhone will be usable with any carrier. Here is a link to a website that will detail the steps with pictures. This will only be an overview of the steps needed to unlock the Apple iPhone.

Instructions

Difficulty: Challenging

1. You will need a program called iNdependence. Once this program is downloaded you will need to jailbreak your iPhone so that you can write files to it thereby unlocking your iPhone. Click "Perform Jailbreak." You will see a picture of a jail cell and text that says "Waiting for Jail Break"
2. This step is the Activation Step. Click on the Activation tab within iNdependence. It will ask for the iPhone firmware files which can be downloaded. Reboot and you should be activated and you can see the iPhone interface.
3. Next, you will need a program from NullRiver called SSH. This might happen from iNdependence, but if not don't be alarmed. Be sure to set up your wi-fi settings because Installer will just download stuff at random, but right now we just want these programs installed in the following order:
   BSD Subsystem (v1.5)
   Community Sources (v2.5)
   Installer (v2.63)
   OpenSSH (v4.6x)
   
   Alright if those apps installed okay you should be able to open SSH on your iPhone (user:root and password:dottie):
   
   ssh [e-mail]
4. Remove the SIM card from your phone as you won't need it till the end. There is a link provided under the "TIPS" section that will allow you to download the file and it corresponds with the steps in this article. Once you download the zip, you will be able to start hacking. Put the files from the zip onto the iPhone into these locations:
   /usr/libexec/lockdownd
   /etc/termcap
   /bin/ice.fls
   /bin/nor
   /bin/iunlock
   /bin/bbupdater
5. Login to iPhone via SSH and execute the following, everything should be fine, but watch for some errors. This step takes about 20 minutes.
   
   chmod +x/bin/iunlock
   chmod +x/bin/bbupdater
   mkdir/usr/local
   mkdir/usr/local/etc
   /bin/launchtl unload
   /system/library/launchdaemons/com.apple.CommCenter.plist
   iunlock ice.fls. nor
   bbupdater -v
6. Now we need to tweak the modem--Use SSH and run
   
   minicom-s
   
   It will say something about a file not being found which is fine. Select "serial port setup" and change "/dev/modem" to "/dev/tty.baseband" and save setup as dfl. and hit exit.
   
   At the command line type:
   
   AT+CLCK="PN",0,"00000000"
   
   and then
   
   AT+CLCK="PN",2
   
   This should result in an OK response from minicom
7. Now reboot your iPhone and put the SIM card in. Congratulations you have just unlocked your iPhone. If not, don't worry; try, try, and try again.
