The cat and mouse game between jailbreakers and Apple continues and is likely to continue even after the release of iPhone OS 3.0. 

Dev team the (un) official supplier of unlock and jailbreak tool of the iPhone has announced that their unlock and jailbreak tools for the iPhone OS 3.0 would be available as soon as Apple releases the software tomorrow.

The team has notified that live demo of yellowSn0w, the iPhone unlock tool would be given before Apple actually releases the software update.

The demo is specifically for people who are using unlocked iPhones and who wishes to upgrade to the new iPhone OS 3.0 when released. 

PwnageTool and QuickPwn tool to jailbreak and unlock iPhone OS 3.0 would also be released after the official release of the iPhone OS 3.0.

However, those of you who are going to get the new iPhone 3G S  and are planning to jailbreak or unlock thereafter have to wait for some more time.
