    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.

    I posted this on another thread...

    I'd like to know how this works. Using this method, couldn't any site install arbitrary software on an iPhone through Safari without the user knowing? Or am I missing something?

    Lost my FaceTime capability after jailbreak.

    Saw this live an hour ago on Twit. Don't do this on an iPad yet. It screwed up Leo Laporte's live.

    Finally. I've really missed iBlacklist, in the first week on iPhone 4 I had too many "should have been blocked" calls.

    Why do ex-girlfirends of many years ago think calling now is a good idea?

    Fun. Of course the same exploit can be used to (maliciously) own your phone from any webpage.

    I wonder if this is exploitable through iAds. And how long would it take anyone to notice such an attack, if it were stealthier than this jailbreak...

    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.

    Here's a good list of Jailbreak applications that are compatible with iOS4 and iPhone4.

    how long did everyone's take? mine has been stuck on "sit tight" for about 15 minutes.

  • by prbuckley on 8/2/10, 5:57 AM

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

    Can anyone recommend the best tethering app for a jailbroken iPhone 4?

    MMS works for me after jailbreaking but the MobileTerminal doesn't run .. it crashes every time I try to load it. Is anybody else experiencing the same issue?

  • by xtac on 8/2/10, 12:06 AM

    I urge anyone looking to do this to:

    1. save your shsh keys locally and to cydia 2. If you are on 4.0 do not upgrade 3. Wait couple more days for reports

    Shouldn't this be posted on Cracker News instead?
