Boy oh boy, it just raining with methods to jailbreak your iDevice today, isn’t it? We just posted how to jailbreak using greenp0ison and now, for your jailbreaking pleasure will detail the process using limera1n, a jailbreak tool developed by Geohot. limera1n will successfully jailbreak the iOS versions 4.0, 4.0.2 and 4.1 and features a rather spartan interface with a single button: “make it ra1n”.
The application is available only for the Windows platform at this point with a MAC version to follow soon. Let’s see how it works in detail:
Step 1: Download limera1n from here.
Step 2: Put your iDevice in DFU mode. For instructions in how to do it, read this article (step 7 in particular).
Step 3: Push “make it ra1n” button and let it work its magic.
Step 4: Reboot when it is done
Step 5: Enjoy your jailbroken device
It is interesting to note that limera1n and greenpois0n are using two different jailbreaking methods and Apple is certainly not happy with iOS security flaws.
