GUIDE: Jailbreak iOS4.1 with sn0wbreeze 2.0.2 (no baseband update) [3G/3GS iPod Touch 1G/2G/3G]

This guide will guide you through the process of creating a custom ipsw file to upgrade to a jailbroken iOS4.1 on your device. This is the Windows equivalent to PwnageTool created by iH8sn0w. Make sure you are already jailbroken and have your SHSH blobs saved on the Cydia server in case you need them to revert back. For this guide, I used an iPhone 3G but you can use any device supported.


Devices supported:

• iPhone 2G
• iPhone 3G
• iPhone 3GS (old bootrom)
• iPod Touch 1G
• iPod Touch 2G
• iPod Touch 3G - running 3.1.2

System requirements for sn0wbreeze:

• Windows XP, Vista or 7 (32 bit or 64 bit)
• .NET framework 2.0
