Not too long ago, iH8sn0w updated Sn0wbreeze to be able to assist in the Jailbreaking of the new bootrom 3GS, iPod touch2G with MC models and iPod touch3G. It will be a Tethered Jailbreak for these iDevices. Again, it will be not easy to Jailbreak these iDevices.
I recommend waiting for Comex to release his Jailbreak software which will support all devices on iOS 4. Most likely he will wait for Apple to release a new firmware ie. 4.01 or 4.1, that will fix the iPhone4′s signal issue.
No other changes for the rest of the devices.
