The iPhone Dev-Team has just released a new version of Redsn0w 0.9.6b1 which can jailbreak iOS 4.1 on iPhone 3G and iPod touch 2G.

Jailbreak iOS 4.1 (2)

This is a beta release of redsn0w for the iPhone3G and iPod Touch 2G at FW 4.1 or 4.0. It uses the same pwnage2 DFU-mode exploit that we’ve been using since the 2.x days. It does not include the SHAtter exploit developed by pod2g. Nothing new is revealed to Apple with this jailbreak.

The Windows version needs further testing, so for now this is available only for Mac OS X x86.

if you have an “MC” model of the ipt2g, your jailbreak will be tethered…sorry! (Consider rolling back to a FW supported by jailbreakme.com or spiritjb.org)

NOTE: If your iPhone 3G relies on Ultrasn0w unlock, stay away from Redsn0w as it updates your baseband to the latest version, making it impossible (for now) to unlock.

Follow the complete instructions posted below to jailbreak iOS 4.1 on iPhone 3G and iPod touch 2G.

Step 1: Download iOS 4.1 for your version of iPhone and iPod touch. Download links are posted below.

Step 2: Update to this latest firmware using the IPSW file you just downloaded via iTunes 10.

Step 3: Start Redsn0w 0.9.6b1 (download link given below) and point it to iOS 4.1 (Final Version) to proceed with the jailbreak.

At this stage you will be presented with a screen where you will have to quickly hold “Power” button and then while holding the “Power” button, you will now have to hold “Home” button too. Now after few seconds release “Power” button but keep holding “Home” button until installation begins.

Step 6: Sit back and enjoy while redsn0w will do all the rest for you. Once done, your iPhone and/or iPod touch will restart automatically and you will find it jailbroken on the latest iOS 4.1 firmware.
