This step-by-step guide and tutorial will show you how to use BlackRa1n RC2 to jailbreak your iPhone or iPod Touch, either on a Mac or a PC. This works for all iDevices, except for the iPod Touch 3G. This tutorial was made using an iPhone 3GS but again, it should work on all devices except the iPT3G.
I already wrote a BlackRa1n tutorial and the steps are identical but a few people emailed me or tweeted me asking to write a tutorial for BlackRa1n RC2.
Before we start, you have to understand that BlackRa1n is a jailbreak and jailbreak only. BlackRa1n will not unlock your iPhone. As a matter of fact, if you want to unlock your iPhone, do not use BlackRa1n as it will update the baseband and make it impossible to unlock for the time being.
How to jailbreak your iPhone with BlackRa1n RC2:
Step 1: Update iTunes to the latest version available and reboot your computer.
Step 2: Download BlackRa1n RC2 from our iPhone downloads page and install it, then reboot your computer.
Step 3: Plug your iPhone in your computer and launch BlackRa1n RC2. Click on “make it ra1n”.
Step 4: Your iPhone will enter recovery mode. The regular recovery mode image on your iPhone will be replaced by a picture of GeoHot (same as image above).
Step 5: BlackRa1n will run on your iPhone and then it will reboot.
A pop up will show up asking you to donate. If you successfully jailbreak your iPhone, I suggest you send $5 or $10 to GeoHot.
Step 6: Once your iPhone reboots, you will have a new icon on your springboard. This is BlackRa1n. Now make sure you have internet connection and launch BlackRa1n on your iPhone.
Step 7: Choose what installer applications you want to install on your iPhone and then tap “Install”. I suggest only installing Cydia but you may install them all if you want to.
BlackRa1n will download and install the selected applications.
Step 8: Once done installing, your iPhone will respring and you should see your installer app on your springboard.
Step 9: Once your installer app (Cydia in our case) is installed. You can safely uninstall BlackRa1n by launching the app and selecting “uninstall balckra1n”.
Step 10: Reboot your iPhone. You’re done!
Hopefully this jailbreak will go more smoothly than with BlackRa1n RC1. If you have any question or comment, please leave a comment below.
