iPhone 4 iOS 5.0.1 Gevey fullauto Unlock (Furiousmod)

Since Baseband version 01.59.00, which was introduced with iOS 4.1 there is no software based unlock for the iPhone 4 available. Gevey jumped in and introduced an hardware unlock; a sim card tray exploiting the way your iPhone validates the SIM. Though it has one big drawback: to use it you need to make a emergency call, enable flightmode, and this on every reboot or sim card switch. If you're iPhone is jailbroken you can avoid the emergency call and the rest of the procedure by using Furiousmod a little mobilesubstrate addon available in cydia (cydia.furiousmod.com). The offical version is at the current state not working with iOS 5.0.1 but thank heavens mcbaron15 posted an fixed version that works like a charm with 5.0.1 on the modmyi.com boards.

Prerequisites:

iPhone 4 with iOS 4.x
PwnageTool
fmod.deb
and some tool to access the iPhones filesystem; iExplorer, iPhoneBrowser, ..

Download iOS 5.0.1 for your device:

iPhone4 (GSM)
iPhone4 (CDMA)

Walkthrough

First we create a custom firmware with the PwnageTool.
Start PwnageTool and select Export Mode. Choose the iPhone and
browse to the the ispw you downloaded.

Make sure in "General settings" the "Enable baseband update" option is disabled (should be disabled and greyed out by default).

Now build the firmware.


When asked save the custom firmware to your desktop.

Connect the iPhone via USB and follow the instructions to enter the DFU mode.


Open iTunes and click on "Restore" holding the "alt" key.


Select the custom firmware from your desktop and wait till your iPhone is updated and the back (i hope you made one before we started) is restored.

Now access the iPhone filesystem and place the fmod.deb in the directory:
/var/root/Media/Cydia/AutoInstall/
Your might have to create the Folders Cydia/AutoInstall in case they dont already exist.
This is the cydia auto installation directory and every .deb you place inside will be installed on the next reboot. Which we do next, after a few seconds you should have a working SIM in your carrier locked iPhone 4. Enjoy!

Although I am a huge Android fan, I do love the Mac OS. I always use this page as a reference. Keep doing what you're doing!

Great stuck! I'm a huge fan of jailbreaks for the iphones. This will be the first place I stop at if I switch over.
