Official iPhone Jailbreak Released

Things move quickly in the iPhone hacking world. While our jailbreak guide works well on Intel Macs, it excludes Windows and PowerPC Mac users. This official jailbreak from the Dev Team follows the same basic inner workings as ours does, give or take a few minor tweaks. The package includes full (again, lengthy) instructions written by drudge and a few tools to perform the jailbreak. Grab it here. It's still fairly difficult at this point, so don't try unless you're experienced.

Jailbreaking will allow you to make changes to the iPhone and install third party applications. Do not use it if you have attempted, successfully or unsuccessfully, to unlock your iPhone. It will become unusable if you do.

Michael,

i used your jailbreak guide without any problems, after reading through the "official" Dev Team guide I noticed that the sym links were cleaned up at the end. I currently have /var/root/Media and /var/root/Media_sym. The phone works fine, AppTapp works and ITunes sync works great.

I am just curious about the cleanup, did I miss something? Will it be a problem down the road?

I'm extremely pleased that you were successful. It's a lot of work and I was concerned that it might be difficult to follow.

As for the "clean up" I actually had you do it, just more conservatively. Instead of removing the symlink, I had you rename it in case we needed it in the future. I figured it would be a handy thing to have around in case something went wrong. It shouldn't hurt anything, either.

Hope that explains it. Enjoy your iPhone!

Thanks for the quick response Michael, and I appraciate any insight you have to offer. I am still a bit confised though as to the use of the Media and Media_sym directories. From what I can see it appears as both are being used and Media_sym is the primary, is that a correct assumption?

Here is a listing of both:

.bash_history .ssh2 Library Media Media_sym

Partitions

After I did the 1.1.1 Jailbreak, I have everything running, but in iTunes, theres no more free space so I cant sync anything.

Did I do something wrong?

It is possible that the iPhone created some of the default files in the root directory because the symlink points to there. If that's the case, I wouldn't worry about it. You shouldn't have any problems.

You need to remove the symlink

Mike,

I have Media and Media_sym in /var/root and I also have Media and Media_sym in /private/var/root. Should I have Media and Media_sym, in both of these folders?

It's the exact same thing. /var/root is a shortcut to /private/var/root
