This guide will provide you step-by-step instructions to jailbreak iPhone 4 and iPhone 3GS using limera1n.

Here are some important points to note before you proceed.

This guide is only for iPhone 4 and iPhone 3GS users.

Please note that jailbreaking your iPhone may void your warranty and hence proceed with caution.

Limera1n supports iOS 4, iOS 4.0.1, iOS 4.0.2 and iOS 4.1.
