The iPhone Dev Team is really serious about cracking the latest software update from Apple Inc. Just a few hours after Apple Inc. launched their iPhone 2.1 update, iPhone Dev Team already released a firmware that would allow users to jailbreak both first and second-generation iPhones that are running on 2.1.

Through this, users may now run their own applications on it. They already have an unofficial site where you get QuickPwn and the Pwnage Tool for the iPhone 2.1 Firmware. Visit http://blog.iphone-dev.org/post/49988701/pwnagetool-and-quickpwn-for-2-1-firmware to know more info.

However, remember that if you jailbreak your iPhone, it might brick the device. Moreover, the warranty could be void.
