UPDATE: The unlock is out. Please read here.
We have been receiving a lot of emails lately asking for a guide to unlock modem firmware or baseband 5.14.02. There are a bunch of new iPhone users who are not very familiar with unlocking using ultrasn0w. Therefore, the guide below will prep you when the new ultrasn0w is due for release before the end of November 2010 anytime between November 22 and 24, 2010.
- You must have a jailbroken iPhone 3G or 3GS. We trust that you may have already done this either with Limera1n or Greenpois0n.
- You must have a working and stable WiFi connection on your iPhone.
Carrier Unlock Steps:
Before you start, please remove the SIM card from your iPhone.
Step 1: Launch Cydia from the springboard.
Step 2: Tap on Manage.
Step 3: Search for ultrasn0w on Packages in Cydia. If you cannot find it, add new Sources by typing: repo666.ultrasn0w.com.
Step 4: A new ultrasnow package will be installed. Once done, go to Packages and look for ultrasnow. Tap and install it. During installation, you will see a black screen with running command lines.
Step 5: Reboot your iPhone and insert your SIM card. Toggle the Airplane mode to ON and then OFF. Your iPhone will search and register to your mobile phone network. Please be patient, sometimes it may take up to 3 minutes.
Congratulations! You have successfully unlocked your iPhone. If you encounter any issue, please leave your comments below.
