Bypass activation and prepare phone for software installation

1. Make sure you have a SIM-card with PIN turned off, and power on your phone (the supplied AT&T card works fine).
2. On the activation screen, slide for emergency and dial: *#301# to make the phone call itself. (If the incoming call dialog quickly disappears but it keeps ringing, just dial 0 (remove *#301# first), and it will call itself)
3. Answer the call, and tap on Hold
4. Phone will call it self again, tap Decline. You will now be returned to the normal dialer.
5. Tap on contacts, and tap the + icon to add a new. The only info you are going to add to this contact are two URL's. To add a URL, tap Add new URL. The first URL is prefs followed by a colon: prefs: and the second is i.unlock.no. Tap Save.
6. Your contact now has two "web pages" - tap on the first one (prefs:). This will take you to the settings dialog. The reason you want this, is because you need to connect to a Wi-Fi network, so tap on Wi-Fi, and get connected to a network, and make sure the icon on top of the screen is indicating that you are connected. While you are in the settings dialog, you should also set: General → Auto-Lock → Never.
7. Now, press the home button, and again, slide for emergency dial 0, Answer the call, Hold and Decline the new call so that you get to the contacts. Tap on your contact (No Name), and this time tap on the other home page, i.unlock.no
8. Safari will launch and show you a webpage. Tap on Tap here to jailbreak your iPhone
9. Phone will return to activation screen and after a few seconds the phone should restart.
10. If the phone does not restart after waiting a full minute, please make sure that you have your phone connected to the computer and try again.
11. When the phone starts again, it should no longer say slide for emergency, but rather Slide to unlock It means it was successfull! Activation is now bypassed, and phone prepared for software installation! (If you are going to use an AT&T SIM, you won't need to do the next step.)

How to jailbreak 1.1.2 or 1.1.3.

Regardless of whether you want to use 1.1.2 or 1.1.3 firmware, you must start with a jailbroken 1.1.1. Downgrade instructions are available here and Jailbreak for 1.1.1 here. When done continue reading here. Note: even if you want to use 1.1.3, you need to upgrade to and jailbreak 1.1.2 first. You should also unlock your 1.1.2 before upgrading.

Upgrading to 1.1.2

1. On a 1.1.1 phone, open Installer and install OktoPrep located in the Tweaks 1.1.1 category.
2. Download the 1.1.2 firmware file from Apple: iPhone1,1_1.1.2_3B48b_Restore.ipsw (right click link and save target)
3. Connect your phone to your computer and open iTunes on the "summary" page.
4. Hold down the SHIFT key (Windows) or Option/ALT-key (Mac) on your keyboard while clicking on the Upgrade button (not the restore button!). A file browsing dialog should appear, and you must select the firmware file you downloaded in the previous step.
5. While the phone is upgrading, download the 1.1.2 jailbreak archive and extract the files to your computer.
6. If you don't already have Java on your computer, you need to download and install Java runtime first. If you are unsure, check the jailbreak.jar file in the archive you extracted previously - it should have an icon with a coffee cup
7. When your phone is done upgrading, and shows the Slide for emergency screen, you need to launch the jailbreak java application on your computer. Windows users double click on the windows.bat file, while Mac users can double click on jailbreak.jar file.
8. An application should appear, with a "Jailbreak" button - click on it and wait while it's jailbreaking. This will take a few minutes, and your phone will restart a few times at the end.
9. Your phone should now show "Slide to unlock" instead of emergency. If it does, everything was successfull.

If are going to use TurboSIM or a similar SIM-adapter you don't need to unlock - it should work right away. If your phone did not have 1.1.2 when you bought it (old bootloader), you can unlock it to work with any sim-card. To do so, install anySIM 1.2.1u located in Utilities category. Open Settings enable Airplane Mode (very important!) (and set Auto lock to never if you haven't already) and then you can launch anySIM and follow the instructions shown.

Important: 1.1.2 has a bug that causes phone/SMS to crash when used in foreign countries. To fix this, you must Install and run iWorld found in the Tweaks (1.1.2) in Installer. Run the application and select your country. When phone has rebooted you can uninstall iWorld.

Upgrading to 1.1.3

This requires that you already have jailbroken 1.1.2. Open Installer, and Install Official 1.1.3 Upgrader found in the System category. This will download the entire 165MB firmware over Wi-Fi, patch it, and upgrade your phone automaticly. So it may take some time - normally 10-30 minutes. When done your phone should reboot directly to a jailbroken 1.1.3 firmware.
