The iPhone Dev Team has finally teased us with a screenshot of the upcoming PwnageTool 4.1 for all iOS devices. This new version of PwnageTool is based on Geohot’s Limera1n bootrom exploit which will allow us to restore custom cooked firmwares (without the upgraded 05.14.04 / 2.10.4 basebands) on almost all the current iOS devices, including: iPhone 4, iPhone 3GS (new bootrom), iPhone 3G, Apple TV, iPad and iPod touch 4G / 3G / 2G. This will enable all iPhone users to unlock using the current version of Ultrasn0w so that they can use the phone on any carrier they like!
GreenPois0n has been updated to add support for jailbreaking iPod touch 2G (MC and Non-MC Model) running iOS 4.1. You can either use Windows, or the Mac version of GreenPois0n RC4 to jailbreak iPod touch 2G on iOS 4.1. Support for iPod touch 2G in Linux version of GreenPois0n will be added soon.
Ex-Chronic Dev Team member pod2g has just discovered another exploit (his fourth) that will pwn iPod touch 2G for life! It’s called the usb_control_msg(0xA1, 1) Exploit. The exploit is different from the SHAtter exploit which is expected to jailbreak iOS 4.1 on the newer iPhone 4 / iPod touch 4G and iPad. It is a buffer overflow that is triggered when a USB control message of the type 0xA1.. oh screw it, if you’re the techy type, you can just read the quote below to see how it works.

Just a quick little heads-up, MuscleNerd of iPhone Dev-Team has confirmed that iOS 4.1 Bootrom exploit which was found by another iPhone hacker named pod2g works on the newly released 4th-gen iPod touch 4G, iPhone 4 and even iPad !
With Sn0wbreeze 1.8 for Windows, you can now create custom firmware files of iOS 4.1 Beta for iPod touches which are already jailbroken on iOS 4.x. Currently, only iPhone 3GS (old bootrom pwned on iOS 4.x, and new bootrom pwned on 3.1.2 or with 3.1.2 SHSH blobs), iPod touch 2G (non-MC model, and already jailbroken on iOS 4.x), and iPod touch 3G and 2G (MC model) pwned on 3.1.2 or with 3.1.2 SHSH blobs are supported. So if you qualify any of these requirements, then you are good to go for a iOS 4.1 Beta jailbreak with sn0wbreeze 1.8. iPhone 3G users will have to jailbreak using Redsn0w, guide for which is posted here.
The first Beta of iOS 4.1 has been released, and the good news is that Redsn0w 0.9.5b5-5 for both Windows and Mac is compatible with this version of iOS. Simply download the required iOS 4.1 firmware file for iPod touch 2G (non-MC model) and use Redsn0w to jailbreak it. This version of Redsn0w of course will work only on iPhone 3G and iPod touch 2G (non-MC model) only.
