Yes, it exploits a flaw in how the iPhone (and OS X presumably) handles PDF files to be able to run arbitrary code. I expect Apple will release an update that closes the hole.

Well, does this mean that most iPhones out there are full of spyware then? And why not?

Presumably not yet. But the blueprints to own any iOS device via a remote web exploit just got put online, with thousands of links pointing to them.

Just did this on an iPhone 4 running iOS 4.0.1. Worked like a charm! Some of the Cydia repositories are being hit hard and may time out the first time you load Cydia (BigBoss especially). Edit: MyWi's USB tethering works, looks like Wifi tethering does not.

Tried wifi tethering and it worked. Although at first it didn't...so I went into settings changed some settings around and then back to how they were at first and hit 'done' and it worked. Sorry for the non-technical explanation but that worked for me.

The installer works by exploiting a bug in the way Safari handles PDF files. A couple years ago, jailbreakme.com was also live but used a TIFF exploit. If you want to see the actual exploit files, go to: http://jailbreakme.modmyi.com/_/ and you will see a list of PDF files by device and OS version.

Out of curiosity...does this information make it easy for apple to stop this method of jb-ing? If so, why publicize details?

The information is very useful for education, and Apple really should fix this, since it's a way to root the device by viewing a PDF.

Will this type of jailbreak let you use the iPhone 4 on a different carrier?

From http://www.iphonehacks.com/2010/08/jailbreakme-20-released-t...

"Update 4:

If you want to unlock your iPhone 3GS and iPhone 3G then you need to first jailbreak your iPhone on iOS 4 or iOS 4.0.1 using JailbreakMe and then install Ultrasn0w 0.93 to unlock your iPhone."

Thank you for providing this, I love this stuff. What site do you read to keep up to date with these things?

Alright so using a pdf analysis tool, here is what it spits out:

Some of that looks like Obj-C to me, what's the other stuff?

If I'm not mistaken, the unsigned configuration profile fix comes with the carrier unlock (not out for the iPhone 4 yet), not the jailbreak.

You're mistaken. I never unlocked my 3GS but had tethering enabled for most of the 3.x lifecycle.

I am pretty sure installing unsigned MobileConfig was disabled in 3.1.2. Maybe you already installed carrier update that has tethering enabled?
