BlackSn0w the application you will be using to unlock your device, BlackSn0w is part of RC3.If you accidentally locked your iPhone on baseband 05.11.07, you will now be able to unlock your iPhone using BlackSn0w. To check what OS version you have and your iPhone and baseband go to Settings/General/About; once you get there scroll down to "Version". The version should be 3.1.2 (7D11).Your baseband is the last on the list, scroll down to "Modem Firmware", it should be 05.11.07. If none of this matches you will need to upgrade to firmware 3.1.2.
This tutorial will only work if you are running OS 3.1.2 on baseband 05.11.07. I will assume that your iPhone is not already jailbroken or unlocked.
Before We Begin You'll
Need The Following:
Make sure you back-up your iPhone in iTunes just for percautions.
Step 1:
Make sure your iPhone is operating on 3.1.2. If you’re running an earlier version download the firmware file above and restore in iTunes. To restore open iTunes with your device connected, click on your device, hold shift and click restore. (For Mac users I believe you hold options and click restore). You will be prompted to open the firmware, select and open it. This will restore your device to 3.1.2, you will lose all your files, make sure you have a backup!
Step 2:
Open BlackRa1n, connect iPhone, make sure iTunes is closed, then go ahead and click "Make it Rain".
Your iPhone will enter recovery mode and you will see the usual recovery image replaced by a picture of GeoHot.
BlackRa1n will run on your iPhone and it will reboot when done.
Step 5:
This message will show up telling you your iPhone has been successfully jailbroken.
After your iPhone has rebooted, you will notice a new BlackRa1n icon on your springboard. Make sure you have an internet connection and launch BlackRa1n.app on your iPhone.
Step 7:
You will now have the option to install Cydia, Rock, or both if you choose to. More importantly, you can also select “sn0w” which is the iPhone unlock for iPhone 3G and 3GS. Select at least Cydia and sn0w, then tap “install”. If you want to unlock an iPhone 2G, DO NOT install BlackSn0w. Simply install Cydia follow this guide.
Once the packages are installed, your iPhone will re-spring and you should see Cydia (and Rock if you chose it) on your springboard.
Step 9: (Only if you want)
Once Cydia and/or Rock, and BlackSn0w are installed on your springboard, you can now uninstall BlackRa1n from your iPhone. Uninstalling BlackRa1n will obviously not remove the jailbreak and unlock. It will simply remove the BlackRa1n.app that was used to install the packages. To do so, simply launch the BlackRa1n.app and select “uninstall BlackRa1n”. After uninstalling BlackRa1n, I suggest you reboot your iPhone.
Done!
The whole process shouldn’t take more than 20 minutes. It definitely is an easy jailbreak and unlock!
