iH8sn0w has released SnOwbreeze 2.3 b1 and is available to download. SnOwbreeze 2.3 b1 has been released to support the jailbreak of iOS 4.3 on Windows OS. But, this is also a tethered jailbreak and so you must use iBooty to keep the jailbreak on every reboot of the device.
SnOwbreeze 2.3 b1 can jailbreak iOS 4.3 on iPhone 4, iPhone 3GS, iPad, iPod Touch 3G and iPod Touch 4G on Windows. SnOwbreeze 2.3 b1 could preserve the baseband, but Ultrasn0w is currently broken on iOS 4.3.
