Jailbreak iPhone 3GS iOS 4 GM with PwnageTool

MSFT.guy has released PwnageTool bundles to jailbreak iPhone iPhone 3GS on iOS 4. These bundles act as a workaround to allow current PwnageTool 3.1.5(Dev-Team official) create iOS 4 custom firmware files for iPhone 3GS, as the PwnageTool averts the baseband upgrade during jailbreak, therefore we can unlock iPhone 3GS by using blacksn0w or Ultrasnow. MSFT.guy has a history of modifying official jailbreak tools to add support for latest firmwares, previously he patched blacksn0w to work with firmware 3.1.3 05.11.07 baseband and recently he modified blacksn0w to unlock iPhone OS 4.0 Beta-4(now knows as iOS 4).
