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 jailbreakme.com. 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, jailbreakme.com
8. Safari will launch and show you a webpage. Read through the text, before you Install AppSnapp
9. Phone will return to activation screen, but don't panic, just wait.
10. Phone should automaticly restart after almost a minute. . If it does not restart withing 2 minutes, click here.
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.)
Unlock the SIM-lock
1. Open installer, and install the update if prompted.
2. Go to sources and tap Edit and Add
3. Add this URL: http://i.unlock.no
4. Tap Done and then Refresh
5. Go to Install (at bottom) and scroll down to the Unlocking Tools category and install AnySIM
6. When installed you can press the home button, and you will find a new AnySIM icon on your home screen. Launch it and follow the instructions.
7. The unlocking process will take about 5-10 minutes, in the end it should say it was successful!
8. To clean up your phone, launch Installer and uninstall AnySIM. Then go to Settings → General → Auto-Lock and set it to a prefered value.
Congratulations, you are done!
A few tweaks
* If you want to enable the International menu, install Enable International menu which is found in the Unlocking Tools category. This will let you choose keyboards, and set your phone to use your prefered regional settings, like date and phone number formatting. Be alerted though - it looks like Apple haven't finished this feature completely yet (which is probably why it's deactivated) so there may be some issues. In my case Fahrenheit and Celsius is mixed up in the Weather application for instance!
* By default, the EDGE settings found in Settings → General → Network → EDGE are not saved when phone is restarted. To fix this, install EDGE Settings fix which is found in the Unlocking Tools category..
* If YouTube does not work ("You must first connect to iTunes..."), try to install YouTube activation which is found in the Unlocking Tools category. Also make sure that the phone has correct date.
* If you for some reason need to deliver your phone to Apple (service etc.), i recommend that you revert the unlock first so that they (hopefully) can't see it's been unlocked. Install OneSIM which is found in the Unlocking Tools category, and tap on the new icon it creates to run it. After you are done, do a restore in iTunes.
