In less then 24 hours after release of the iPhone OS 4.0 Developer Preview, iPhone Dev Team member MuscleNerd has successfully jail-broken the operating-system and installed Veency VNC application on the iDevice.

MuscleNerd also posted a video showing the jailbroken iPhone OS 4.0 running Veency (A Cydia hosted app), you can checkout the video as posted ahead. There is no expected time-frame for a public release but things look very much on track and an proper iPhone OS 4.0 Jailbreak seems eminent in future.

Apple iPhone OS 4.0 will not be available to end-users before summer 2010, However, Apple has made available the beta build of the OS to developers registered with them - but for the adventurous users out there they can now download iPhone OS 4.0 Beta 1 as it is now leaked and posted on internet by iModZone.net.

But even if you download iPhone OS 4.0 Beta you still need to have your Device id registered with an dev Account and live up with an non-jailbroken phone as we don't have any working iPhone OS 4.0 jailbreak now, the good news is there is a un-confirmed way to get your device registered with an developer account as shown next.

The cat is finally out of the bag as Apple announced the iPhone OS 4.0 update, here we have a list of most important new features and updates introduced in the Apple mobile OS platform complete with a video walk-through.
