MMi member moderator StealthBravo has released a patched Quickpwn utilizing a beta 4 3G bundle cracked by HoZy and lilstevie. The current version is iPhone 3g only! The jailbreak is Windows only (packaged in windows QuickPWN).

Like the previous 3.0 beta jailbreaks this one installs Icy (Cydia isn't ready yet). Also like previous 3.0 beta jailbreaks you need to have your iPhones UDID in a dev account. StealthBravo has also put together instructions to troubleshoot common problems in his huge Firmware 3.0 jailbreak thread.
