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.
Redsn0w 0.9.6 is now available for Windows. You can use it to jailbreak iPhone 3G and iPod touch 2G on iOS 4.1. 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.
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.
Most of you might have already know by now that an all-iOS device jailbreak called JailbreakMe 2.0 (Star) has been released. This new tool utilizes userland jailbreak vulnerability which enables it to jailbreak any iOS device on the latest firmware right from the Safari browser. More details on the jailbreak can be found here, and here.
Sn0wbreeze 1.7 for 4.0 has been released. Just like PwnageTool 4.0 / 4.01 for Macs, you can now create custom pwned / jailbroken ipsw files on Windows too which can now jailbreak all iOS devices (except iPhone 4) on iOS 4, including iPhone 3GS (new bootrom), iPod touch 2G (MC models) and iPod touch 3G. But there is a catch to it! You will need to have their SHSH blobs saved for iOS 3.1.2 in order to successfully jailbreak these devices on iOS 4. Also the jailbreak for iPhone 3GS (new bootrom), iPod touch 2G (MC models) and iPod touch 3G on iOS 4 will be tethered, which means whenever you turn off your phone, you will need to re-connect it to a computer to be able to turn it back on.
With Sn0wbreeze 1.6.1 for Windows, you can now create custom firmware files of iOS 4 which are already jailbroken just like what PwnageTool 4.0 / 4.01 can do on a Mac. Currently, only iPod touch 2G (non-MC model, and already jailbroken on anything other than Spirit) can be jailbroken on the newly released iOS 4. Both the iPod touch 2G (MC model) and iPod touch 3G requires a new exploit which is currently not available. So if you haven't already jailbroken your iPod touch 2G with Redsn0w, you can do so with sn0wbreeze 1.6.1 for 4.0.
