The latest iPhone 3.0 beta 3 firmware has noticeably improved in speed and performance so it’s worth the update. As of right now you can only jailbreak on the iPhone 3.0 Beta 3, iPhone 3G 3.0 beta 3, and iPod Touch 1st Gen 3.0 beta 3 firmware. Support for iPod Touch 2nd gen has not been added. Saurik is working on adding support for Cydia on iPhone OS 3.0 so it won’t work yet. Jailbreaking with this QuickPWN release will install the Icy app created by RipDev. Once you’ve jailbroken you can launch Icy, refresh the sources and install OpenSSH to SSH into it.
