Well if you are on Windows and looking forward to jailbreak iOS 5 Beta then here is PwnageTool for Mac alternative Sn0wbreeze 2.8b1 from iH8sn0w updated to support iOS 5 Beta jailbreak on Windows. Like Redsn0w 0.9.8b1, Sn0wbreeze 2.8b1 is also tethered jailbreak and requires iBooty to tethered boot every time you reboot your iOS device running iOS 5 Beta.
Sn0wbreeze 2.8b1 supports iOS 5 jailbreak on following devices,
iPhone 4 [GSM]
iPhone 4 [CDMA]
iPod Touch 3G
iPod Touch 4G
Please keep in mind that Sn0wbreeze 2.8b1 does NOT add afc2 or hacktivate to prevent users from removing the UDID check after jailbreak. Also if you rely on carrier unlock then you must stay away from iOS 5 beta
