[How To] Jailbreak iPhone 3G With iOS 4.1 Using Redsn0w (Mac Only)

RedSn0w is the popular jailbreaking tool which was developed by the iPhone Dev Team. The team released RedSn0w version 0.9.6b1 earlier this week, which allows iPhone 3G users to jailbreak iOS 4.1.

In this guide, we will help you with a step by step procedure on how to jailbreak iOS 4.1 for the iPhone 3G.

Important:

Before you continue, here are some points to note:

• Please note that jailbreaking your iPhone may void your warranty and hence proceed with caution.
• Do not forget to backup your iPhone before you proceed. (Just sync everything with iTunes once before doing anything).
• Please note that this guide is only meant for Mac users. Windows version of Redsn0w is currently not available. However, Windows users can checkout Sn0wbreeze instead.
• If you want to unlock your iPhone then do NOT use Redsn0w. Redsn0w will NOT unlock your iPhone 3G. We suggest you use Sn0wbreeze as it protects the baseband and then use Ultrasn0w to unlock your iPhone 3G after you have successfully updated and jailbroken iOS 4.1. Mac users should wait for iPhone Dev Team to releasePwnageTool.
• Please ensure you are running iTunes 9.2 or later.
• Redsn0w does not work on iPhone 3GS or iPhone 4.

‘Verbose boot‘ offers detailed booting information to users. This may not be necessary for common users and need not be selected. You may also choose to not check ‘Custom boot logo‘ and ‘Custom recovery logo‘ options if you prefer the default icons. However, if you wish to provide your own boot and recovery logos, do remember that these images have to be PNG files in RGB or grayscale mode and inside 320×480 resolution.
