I will post a very easy tutorial of Dev Team Unlock for Mac

-First you will need to install the app from nullriver, once you have it on the iphone open it and install things in this order:
-Second you will have to have an already activated iphone , if you dont have it activated use this method for mac :http://hackint0sh.org/forum/showthread.php?t=5582
-BSD Subsystem
-OpenSSH
-Open Terminal

IMPORTANT ADVISE :
i used itunes 7.4 to unlock my phones! and no problem guys remember TO COPY THE "com.apple.CommCenter.plist " TO YOUR MAC BEFORE STARTING ALL THE PROCESS THEN DELETE IT FROM IPHONE SHUTDOWN THE IPHONE AND THEN TURN IT BACK ON! THIS IS VERY IMPORTANT!!! AND IF YOU GET CONNECTION REFUSED FROM FUGU CHANGE THE STATIC IP ADRESS YOU CHOOSE AT THE IPHONE!! AND REMEMBER THAT WHEN YOUR ARE FINISHED PUT BACK THE "com.apple.CommCenter.plist " TO YOUR IPHONE AND REBOOT IT AGAIN !!

Then you need to install FUGU on your Mac once you have it go back to the iphone, se the iPhone for having a Static IP adress and set it so it will never get lock! now you are ready to open FUGU at your Mac, im going to post the steps once FUGU is open on your Mac:
-type the iPhone IP adress you set on it earlier
-it will ask you for the password of the iPhone, the password is "dottie"
-now you are inside the iphone system go to "usr" folder of the iphone
-create a new folder on the iphone called "local, open it and create inside it a new folder called "etc"
- go back to usr folder on the iphone and now get into the "bin" folder located inside "usr" folder, here you have to upload three files, "iunlock", "ICE03.14.08_G.fls" and "nor"
-now get back to the intiall folder inside your iPhone and get into your "bin" folder (not the one inside usr folder), here you have to upload the bbupdater
-now get back to the initiall folder of the iPhone and get into your "system" folder, once inside it open the "library" folder and then open the "launch deamons" folder here you will see this file "com.apple.CommCenter.plist" copy that file yo your computer and then erased it from the iphone.
-Now you have to shutdown your iphone, and then restart it
-Once the iPhone is on and connected to the Wifi open the terminal in your Mac and type this to get into the iPhone "ssh -l root here you wright your ip adress" then enter/return
-now it will ask you the password type "dottie" enter/return
- once inside the iphone type "cd /usr/bin" enter/return
-"minicom -s" enter/return
- Select "Serial port setup" (with your down arrow key) then press enter/return.
-At the next screen, type: A
-Your cursor will now be at the "Serial Device" line. Type: /dev/tty.baseband Then press enter/return.
-Press the escape key. Select "Save setup as dfl" and press enter/return. You will get a pop up message saying "Configuration Saved".
-Select "Exit". Then press enter/return. then close that terminal window
-Open a new terminal window and type "cd /usr/bin" enter/return
- type "iUnlock ICE03.14.08_G.fls nor" enter/return, the iphone should take like 20 minutes to get this process done
-once its finished type "bbupdater -v" enter/return
-now type "minicom" enter/return
-type "AT" enter/returnyou should get OK for response
-type AT+CLCK="PN",0,"00000000" enter/return you should get OK for response
-type AT+CLCK="PN",2 enter/return you should get this for response "+CLCK: 0
OK", if this is the case your iPhone is unlocked
-now open again the FUGU on your mac log into your iphone the same way you did it before
-go to "system", "library", "launch deamons" and inside that folder put back the "com.apple.CommCenter.plist" you copied before to your mac now closed fugu, shutdown your iphone, put inside it any sim card you want , then turn it on and i should work!

IMPORTANT:!!!
guys if you get this message from FUGU "WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED"! guys if you get this error an the beggining (during the first time you try to connect to your iphone) the solution is simple just go back to the iphone and type on it a different Static IP then go back to FUGU type the new IP adress and that should work!
thats all! is not that hard if you follow step by step! inclusively you could copy the commands i have written ! remember enter/return means type that key of your keyboard after typing what is beetwen the ""

good luck and hope this helps you!

THANKS TO ALL THE DEV TEAM FOR THEIR GREAT JOB AND EFFORT! I WOULD LIKE TO GIVE SPECIAL THANKS TO SAM HE HAS BEEN HELPING ME WITH SOME ISSUES I HAD ON MY IPHONE HE IS SUCH A GREAT GUY!

CHEERS DEV TEAM!

TY this is the one of many tutorials i took but this one accually worked!!

Really stupd question - I cannot see 'OpenSSH' in Installer - do i need to point to another soirce ?

SSH is installed though independence if your using a mac, not sure for windows.

Oh OK - i've having massive SSH/SFTP probs so thpught maybe using a different SSH client would solve them. thanks anyway

I just got some wierd WARNIG host change middle man possible attack or something... please help, need to get this working... this all happened just when I ws loggin on thorugh termi
first step

this is after I did all the FUGU stuff and had no problem loggin on...

Why didn't you upload bbupdater to /usr/bin? According to this tutorial, one should upload it to /usr/bin along with all other files.

This step is not needed if you do

before running iunlock. and executing

after the unlock is done.

here it is....
