Jay Freeman, better known as Saurik, the creator of Cydia, was interviewed by the home radio Make It Work. He speaks about the history and the future of the iPhone jailbreak.

Saurik describes the origins of Jailbreak and Unlock for the very first model of the iPhone. Jay explains that initially there were two important things to do with the iPhone 2G -- to use other carrier than AT&T and to install any application.
He continues discussing the main applications from Cydia. Cycorder was the first to allow video recording, and Winterboard was the only one that allowed users to change the graphical interface of the iPhone. He also speaks about Comex, the hacker who is currently working with the Dev Team for releasing and Unlock for the . According to Saurik the tool is still not ready to be released to the public due to severe bugs in the code. Here the second part:
DevTeam hacker Planetbeing has just announced that the has been successfully unlocked.
Looks like I now have an unlocked iPhone 4. 🙂
My soft-unlocked iPhone 4 (in Canada). I’ll have video in a couple of hours once I can top-up the SIM. http://twitpic.com/24ycdv
DevTeam congratulated planetbeing in team’s official twitter:
Congrats to @planetbeing for first ever soft-unlocked iPhone4 http://is.gd/dqwvv (now to streamline it!)
Musclenerd also mentioned one interesting fact:
We think we have 3 different ways to unlock once inside BB (the 3rd way was first to fully work for @planetbeing !)
Congratulations for accomplishing this in such a short time. The unlock will be publicly available shortly after comex releases his jailbreak utility for iOS 4.
iH8Sn0w has successfully performed a tethered jailbreak for iPhone 3GS with new firmware iOS 4 and the new bootrom. Unfortunately this jailbreak requires users to have 3.1.2 SHSH blobs saved.
Alright… If anyone has their 3.1.2 SHSH blobs, NOT 3.1.3. Then I’ll see if I can produce a tool that will do this job…
Here is a video demo posted by AKinGdom1:
The utility will be available soon. Might be as soon as tomorrow.
Hacker msftguy created unofficial PwnageTool which allows to upgrade to the pre-release of iOS 4.0 GM while keeping your jailbreak and old baseband.
This is not an official release by Devteam, so we recommend to wait for the final versions of both iOS 4.0 and PwnageTool.
For the advanced users who want to experiment here is a .

iPad USB Camera Connection Kit is much more useful as it seems. Max Sha, an experienced user, was able to access external hard drive with this kit. All you need is a jailbroken iPad, an external drive, a split-USB cable to give the drive some power and a terminal of some sort (f.e. MacBook) to mount the external storage. While it is a little unwieldy, it shows that Terabytes of external storage for iPad is possible.
Here is a complete step-by-step guide from Max Sha:

Finally the jailbreak for iPad, iPhone and iPod Touch from the Dev Team is available for download. It’s free and untethered and it’s called “Spirit”. The jailbreak supports every iDevice with firmware version 3.1.2, 3.1.3 or 3.2.

Wow! Hours after iPad 3G sales launch and it has already been jailbroken! Below is a video of MuscleNerd where jailbroken iPad 3G runs Cydia.
MuscleNerd used the jailbreak called “Spirit”. It’s a tool that makes untethered unlock of iPad, iPod Touch 3G and iPhone 3GS and DevTeam promises it will be available soon. Stay tuned for further instructions how to save your SHSH Blobs and then use Spirit to jailbreak your device.
