I just tried it… and it works… rather more than less!

So for you guys who want to unlock your iPhone 3G, there are a few steps to follow to accomplish this:

- With iTunes, update (or restore, if you want to loose all your settings) your iPhone to the latest Firmware (2.2)

- Then, quit iTunes and download QuickPwn 2.2 from here

- Launch QuickPwn 2.2 and follow the onscreen instructions. This software will basically activate your iPhone, allow read/write access (jailbreak) and install Cydia, the equivalent of the Appstore for unofficial apps

- After your iPhone has been cracked by QuickPwn (it takes a few minutes), you will have new icons, including Cydia. Launch it.

- It will work some time and you will have to relaunch it. Also, do the updates if any are available.

- After that, in Cydia, go to “Sections” and select “Repositories” and add the “iClarified” and “iPhone-notes.de” repositories. It will take some time to refresh the sources.

- Go to “Manage”, tap “Edit” and “Add”. You will then enter the Dev-Team repository: http://apt9.yellowsn0w.com. It will again refresh.

- Go back to “Sections” and select “Tweaks”. Install “APN Editing”. This will allow you to manually edit the data connection settings for your operator.

- Finally, go to “Search” and type “yellowsn0w”. Install the unlock tool. NB: currently, the tool does not support SIM cards with PIN codes. So remove your PIN code (quit Cydia and change it in “Settings”/”Phone”/ “SIM PIN”) BEFORE installing Yellowsn0w!!

- Quit Cydia, go to “Settings” / “General” / “Network” / “Cellular Data Network” and put the correct settings for your GSM operator (Swisscom: APN=gprs.swisscom.ch, leave User and Password empty / Orange: APN=internet, leave User and Password empty / Sunrise: APN=internet, leave User and Password empty)

- Reboot your phone and that’s it!

(Edit) Be very careful with your data traffic if you don’t have a specific data plan including some traffic!! If you want to avoid any traffic, leave the APN settings empty!!

(Edit 2) I couldn’t have 3G working correctly with the unlock tool. Data network is working, the 3G icon is visible, but I only get GPRS/EDGE speed… Hope they will fix the bug

(Edit 3) I seems to work better, if, once you’ve finished the steps above, you do a few more:

- Once you’ve rebooted the phone, reset the network settings (in Settings / General / Reset)

- Then turn on Airplane mode… wait 30 seconds… and turn it off again

- Take out your SIM…. wait 30 seconds… and put it back in

- wait 30 seconds…

With these steps, my phone was working correctly on Swisscom Network with an Orange SIM locked phone

First, as it is said in the title, this tutorial is only for the upgrade and unlocking of original iPhones (with metallic back) to iPhone OS 2.0. The process for 3G is slightly different and I will post the tutorial soon!

And, obviously, you do all this at your own risks!!

So, where to start?

1. You need to get the OS system file (iPhone1,1_2.0_5A347_Restore.ipsw). To do that, start iTunes 7.7 (if you have an earlier version, please update), plug your iPhone in and check for update. iTunes will find an update and ask if you want to update your iPhone. Click “Yes” and once the download has started, UNPLUG YOUR IPHONE!! Wait until the download has completed and then quit iTunes.

2. (Optional) If you don’t want to be annoyed by iTunes all the time, kill iTunesHelper (open Activity Monitor (in Utilities) and “Force quit” the iTunesHelper process). iTunes will stay quiet until next time you restart your machine…

3. Plug again your iPhone to your computer, start Pwnage Tool 2.01 (download Pwnage_2_01, including the bootloader files) and select “Expert mode” and the iPhone image on the left. Then click on the right arrow.

4. On the next screen, Pwnage will search (and find ) the 2.0 system file that iTunes downloaded in step 1. Click on the right arrow to continue.

5. On the next screen, double click on “Custom Logos” if you don’t want the application to replace the “Apple” boot logo with a pinapple….

6. Deselect “Boot logo ” and “Recovery logo”.

7. Click on the blue arrow to go back to the main menu. Select “Build” and click on the right arrow to start the building of the new system file. You will be asked to save the new file on your disk.

8. Wait until the process is finished. You will then be prompted to “Pwn” your iPhone. Click “No” to proceed.

9. You will be asked to switch off your iPhone and put it in recovery mode. Simply follow the on-screen instructions to make sure it works out!

10. Once this is all done, you can quit Pwnage Tool and restore the newly created system … with iTunes!

11. Start iTunes, click “Restore” while holding the “Option” key on your keyboard. Select the “.ipsw” file that was created by Pwnage Tool and let the magic happen!

12. Once the restore is completed, iTunes tells you that your phone will reboot. Quit iTunes quickly while your phone reboots.

13. Once it has rebooted, the iPhone starts a few applications that will unlock it. Just let it complete the process (it takes a few minutes), the iPhone will reboot… and that’s it!! Enjoy!!

But, be aware: the process is not as simple as ZiPhone… Be careful!

And, I have only tested it on my 1st gen iPhone. Haven’t received my 3G iPhone yet !

Basically, the principle of the Pwnage tool is quite easy:

1. You “PWN” your iPhone running system 1.1.4: this operation alters the phone’s bootloader and “breaks” the check of signed software. After this operation, the phone will let you install any unsigned ipsw file via iTunes.

2. You create a custom 2.0 system file that will activate, jailbreak (=make the system read/write) and unlock the baseband (allowing it to run on any GSM carrier).

3. You put your phone in recovery mode, and restore the custom IPSW file directly from iTunes

4. Once it’s done, the phone unlocks itself and here we go!

So far, everything worked fine on mine, including AppStore!

You can download all the stuff needed (for Mac…) here: Pwnage 2

A full tutorial (with screenshots) will follow soon!

Here are the unlocking instructions (careful, very difficult.. ):

- Make sure you don’t have a phone that was initially unsimlocked with anySIM 1.0 or similar. If it is the case, virginize you phone first (google “virginize iPhone” to learn how to do that). I think ZiPhone can do it but I never tried…

- Download the firmware file you need from Apple (links can be found here) and, with iTunes, restore (yes, restore) your iPhone to the firmware version you just downloaded (click on “restore” while holding the “alt” key on Mac or “shift” on PC)

- Once the restore is finished, download ZiPhone 2.5 from here.

- Launch ZiPhone and click on “Do it all”. For more advanced users, read the instructions of ZiPhone.

- After a few minutes, your phone is unlocked and ready to use. Insert your SIM card and here we go!

- I still recommend you do the following to iPhone in peace: connect to a WiFi network, launch installer and install 2 things: in “System” install “BSD subsystem”, and in “iClarified”, install “AppSupport patch (1.1.4)”.

That’s it!! … and don’t forget not to update when the next firmware version is out!
