Overnight, what has to be the easiest ever jailbreak ever produced, was released.  Produced by @comexJailbreakMe” is a browser based jailbreak mechanism for your iPhone, iPad and ITouch.  The only requirement being your iDevice should be running firmware 3.1.2 or newer.

It really couldn’t be a simpler process to undertake.  Simply open Safari on your iDevice, browse to and then slide your finger across the screen to start the jailbreak process.  (You are recommended to backup your iDevice before you begin).

Reported issues

Not long after JailbreakMe was released there were reports of Facetime not working and MMS functionality being missing.  These issues have now been rectified by the jailbreak team.  If you jailbreak from here on in, you won’t have the problem.  If you jailbroke your device within the first few hours of JailbreakMe’s release, then simply run a Cydia update and you’ll be back in business again.

If, when running the installer, you get a purple screen, hard reboot your iDevice (press and hold both home and power until you see the white Apple logo) and start again.  This can happen when the jailbreak servers are under huge load due to sheer demand for the jailbreaking toolset.  If you still continue to get a purple screen try the following:

  • Go to Settings > Safari > Clear History, Clear Cookies, Clear Cache
  • Reboot your iPhone
  • Try again

Sim Unlock

The sim unlock to accompany this release (Ultrasn0w) should be available within the next 48 hours.  The jailbreak team are currently undertaking a private beta of the latest iPhone 4 ready tool so they can iron out any last minute issues.

Ensuring you can always jailbreak iOS4

It won’t be long before Apple close the hole that the jailbreak team are currently exploiting.  To ensure you are always able to jailbreak your iOS4 device, you should save what are referred to as your SHSH blobs as soon as humanly possible.  Cydia does this for you automatically when you’ve a jailbroken device; however the best way to do so is with a simple tool called Firmware Umbrella.

Advice about installing jailbroken applications

At the time of writing you will find that not all of the software that’s available on the Cydia or Rock repositories has been updated to work with iOS4.  As such, I would recommend you review this Google App Spreadsheet or alternatively this wiki page, to see if something is safe to use.  If you install something that’s not compatible, there’s every chance your iDevice will crash and require a restore before you can use it again.


Making the jailbreak simple, so much so that anyone can use it, isn’t a bad thing.  It makes the jailbroken world so much more available to even more people.  It’s early days, but the only two downsides I can currently see to this process are:

  • The potential extra resource drain on your battery (haven’t had enough time what it’s like yet).
  • If you want to remove the jailbreak, you have to do a full restore and when you do so, your user data isn’t (reportedly) preserved.  i.e. settings for applications.

Have you jailbroken your iPad, iPhone or iTouch using this process?  How did it go for you?  Are you delighted to finally be able to use your iPhone 4 or iPad with the wonderful applications and tools available via the Cydia platform?  Please share with us your experiences in the comments section below.

  • Well it certainly the easiest way to jailbreak ever. But I am going to hang on at least for the time being. One of the things I have always loved about the iPhone is how solid and stable it is in use. Over the 12 months I had my iPhone 3G S it never crashed or slowed down. It is early days yet for my iPhone 4 but I don't to to endure the crashes, freeze ups and slowdowns that other phones seem to develop and some jailbroken iPhone users complain of. Also I want to see what happens with iOS 4,1 when it is released in the few days.
    Maybe then I will take the plunge.

    I'm not going to dress it up for you: when I was jailbroken there were occasions when I had my iPhone crash. It was an iPhone 3G and in all honesty I was asking too much of it with the applications I asked it to run, and many at the same time. I expect more of my iPhone 4. The main reason I have jailbroken? The ability to unrestrict it so it thinks I'm on wifi when I'm actually on 3G services, and more importantly, the application SBSettings. I really miss the ability to toggle things such as wifi and Bluetooth on and off with a quick tap. Navigating through the deep menu system can be so cumbersome!

  • I did mine last night. Worked a treat and very simple.

    My 3GS tends to crash fairly regularly when playing music in the car. Rarely crashes at other times. This has not changed when jailbroken or not…so for me, no difference when jailbroken.

    I wonder if that's because the iPhone doesn't like your iTrip?

  • I would be somewhat annoyed if it decided that it didn't like my simple 3.5mm plug that goes into the cassette player in my car. Yes, that's right. I have a cassette player. Much easier than using iTrip or anything else for me!

  • Rob

    Actually, that's probably the best way – unless of course you have
    direct iPhone cable to stereo since you aren't subject to frustrating
    interference that the iTrip suffers!
