Blackra1n for iPhone firmware ver 3.1.2 baseband 5.11.07
To check for version and baseband just click on Settings-general-about
your version is under version and your baseband is under modem firmware
works with iPhone 2g, 3g, and 3gs
I tested it with iPhone 2g and 3g
1.Plug in your iphone to your computer
2.After your device is detected open blackra1n(you don't need to have itunes up)
3.Click on make it ra1n
4.Your phone will freeze for a second and reboot
5.Once it's done rebooting you'll notice that a new icon has appeared called blackra1n.
Click on that and install Rock or cydia.
6.Your phone is jailbroken!!!
7.(optional unlock for 3g and 3gs only)If you clicked on blackra1n you'll notice a third icon called
blacksnow. If you install that it will unlock your phone.
8.(optional unlock for 2g only)Once you install cydia/rock, click on it and search for bootneuter.
Once you download and install it, click on it and the settings you need should auto propigate. Click on flash and
and wait for your iPhone to reboot. Voila your iPhone is now unlocked!
Warning! Do not! I repeat! Do not upgrade your carrier settings when itunes asks. This will brick your
iphone. I should know, I did it twice before I learned my lesson. You'll have to restore your
iphone if you upgrade your carrier settings to unbrick your iphone. I am not responsible for what happens to your iPhone.
