The 3G jailbreak for iOS4.1 has been released. Unlockers have been advised to stay away as updating to 4.1 will update your baseband. But I wonder if you could use TinyUmbrella to update a 3G to 4.1, preserving the baseband, and then jailbreaking with redsn0w. An unlock would be possible, right? EDIT: actually nevermind. Just read that it only preserves the iPhone 4 baseband. My bad.
