Planetbeing member of The iPhone Dev Team has successfully jailbroken the iPhone 4 using fellow jailbreaker comex’s userland jailbreak code!. Above is a high resolution Screenshoot showing the iPhone 4 with Cydia.

Unfortunately, not only that this jailbreak is far from ready,  p0sixninja says that this jailbreak cannot be released publicly as it contains some of Apple’s software.

Think I’m the first one I know about to get a root shell (and SSH) on iPhone 4, using poor @comex’s code (since he has no iPhone 4).

Congrats to @comex for another userland JB http://is.gd/d5N6I hi-res Cydia via @planetbeing & @chpwn iPhone4s.

The jailbreak shown is a more of a stepping stone for us, it can’t be released because it includes some of apples software,
