The latest version of Redsn0w has been confirmed to jailbreak the just released iOS 4.3.5/4.2.10 on iPhone 4, 3GS, iPad 1, and iPod Touch 4G/3G. But it will be limited to tethered boot, which means you will have to reconnect your device to your computer every time you reboot your iOS device. iPad 2 is obviously not supported
