The iPhone Dev-Team has released a version of Redsn0w for Windows that can jailbreak the iPod touch 2g and iPhone 3G on iOS 4 using Windows.
MuscleNerd: redsn0w 4.0 JB now available for Windows http://is.gd/cSXNN ... ipt2g and iPhone3G (but no hactivation til public 4.0).
The redsn0w beta has been updated for 4.0GM on iPhone 3G and iPod touch 2G (non-MC version). Multitasking and homescreen wallpaper are turned on by default (Apple doesn't normally allow this on these 2 devices). You can deselect these features if you choose.
A version for Windows is now provided.
Just like our other betas, this one intentionally doesn't “hactivate” the iPhone. Please wait for Apple's public release of 4.0 for that part of it.
YOU SHOULD STAY CLEAR OF THIS BETA SOFTWARE IF YOU RELY ON A CARRIER UNLOCK. That's because the beta redsn0w works only if your device has already been upgraded to the stock 4.0beta1/beta4/GM IPSW from Apple, which contains a baseband update. If you installed that IPSW, you've already lost the carrier unlock until the next planned release of ultrasn0w and blacksn0w.
We will be updating our tutorials as soon as the final version of the 4.0 firmware is available. In the meanwhile use this redsn0w tutorial to guide you.
