Jailbreak in the wild for iOS4 devices

TiPb reports a new jailbreak designed for Apple devices running iOS4 has been released.

The jailbreak, created by a user under the alias of comex, is accessed on a iOS4 device via Safari by navigating the browser to jailbreakme.com. Using a fancy web-based interface, a user simply slides their finger across the screen to perform the jailbreak.

A note of caution, reports are coming in that some have bricked their phones using this jailbreak, or are missing features such as Facetime and MMS. Please remember this before performing the jailbreak. Performing a backup is also always highly recommended before attempting a change such as this. A hard restore may correct issues stemming from a botched jailbreak. As expected, jailbreakme.com is experiencing a high load, and performance may be sluggish. This could be the cause behind the hit and miss bricking issues the jailbreak creates.

Currently ultrasn0w and other soft carrier unlocks do not work as of yet.

Redmond Pie has complied a list of all devices currently able to utilize the jailbreak.

Have you successfully jail broken your iOS4 device? Let us know in the comments!

 

[Update] A reader has tipped us off that this may be a fix for the MMS and FaceTime issues some have been plagued with:  "If you backed up BEFORE the jailbreak you can right click the iPhone icon and select Restore From Backup. The Settings will be overwritten and MMS, Facetime and Cydia will all be there"  Thanks 0sm3l

Did it on a 3Gs with 3.1.2 and works fine.
First try safari crashed then second try it took maybe 2-3 minutes and done.

The pixels on the boot screen are not a watermark. It's the actual jailbreak as it uses a frame buffer overflow when booting. So when you see the pixels on the boot screen what your actually seeing is the jailbreak itself

You can install this to sort of fix the exploit if you have JBed the phone. It won't plug the hole, but it will prompt you if it's attempted to be used.

If you get stuck at the purple screen all you need to do is the following:
Close Safari
Double Click Home and close Safari in the task switcher (If you have a 3GS or higher or an iDevice which has multitasking)
Go to settings and clear Safari's cache and cookies and try again.
It'll work eventually.

Some apps don't work in 4.0 yet and can cause your phone to stay in safe mode, to fix it just uninstall the app(s) that you last installed or which triggered it.

The compatibility list that was linked to on ModMyI is horribly out of date (At least the OP is)

Some of the Cydia apps don't appear to be working yet.
Notifier (doesn't notify!)
MobileTerminal (crashes as soon as you launch it)

It's not working on my 3g for some reason, just shows the wallpaper on the mobile site and if I try to refresh it the site says "Oops... it looks like the installer crashed the last time you tried to jailbreak. "

Working on 3GS 4.0.1. No reason to really do this for me other than terminal & SSH as 4.0 solved all my UI needs.

Discussion of jailbreaking is fine... as long as it doesn't involve any illicit software or warez. Keep it clean!

Must be chaos in the Apple stores all around the planet...
Just walk into one and jailbreak their demo iPhone 4 - and it is perfectly legal

Ha, that's the first thing I thought of when I saw this.

Anyone else get some weird looking dead pixels up the top when they turn phone on/off? Its just above the apple logo, so weird wasn't there before I JB'ed. I have had to restore to factory defaults after this as well because it would only boot into safe mode Springboard kept crashing.. It was after I install MyWi though dunno what that did.

Yeah I get dead pixels on startup as well. At least I'm not alone.

Someone commented on this on the Dev blog looks like a watermark by comex

I thought Apple was going to put in a watermark if your iDevice is jailbroken. Or is that a rumor?
And is he going to remove the watermark ever?

there is on update on Cydia now which fixes the MMS/Facetime issue. Just install update and reboot...and works brilliantly!

When I slide the slider to jailbreak, nothing happens. Only the background stays and that's it. Any help?
I"m getting this as well.

I finally got it to work. My thought is that the servers are getting pounded right now.

does the download screen pop up immediately or should i wait for a quick minute on that background screen?

it pops up quick, about 10secs if not faster.

This is actually a *bad* thing, despite it opening up jailbreaking capability for the iPhone 4. This is a userland exploit that can be executed from a web browser, which means 1. it's only a matter of time before this is exploited for nefarious purposes, and 2. Apple has a reason aside from petty jailbreak prevention to fix this. Additionally, it works on OS 3 - so the exploit can be used for nefarious purposes on the iPhone Edge as well, and they have no option aside from to buy a new phone, to fix it.

Can't someone incorporate this code into their popular blogs/website and make it auto-activating so that it frees the world from Apple. Might brick a few phones along the way, but collateral damage.

For people with MMS/FaceTime issues:

If you backed up BEFORE the jailbreak you can right click the iPhone icon and select Restore From Backup. The Settings will be overwritten and MMS, Facetime and Cydia will all be there. It worked for me.

Tried it, and it failed to make mms or facetime work again (and yes i used the last backup from before the jailbreak)

Though i see from Twitter that it does indeed work for some people

weird... it seems to work for a few people I told. Is it an iPhone 4? You could also try resetting the settings inside the iPhone. (Settings -> General -> Reset -> Reset All Settings). Let me know.

Yup it's an iPhone 4

wont bother with this jail break seeing as updateing to 3.1.3 from 3.0.1 killed my wifi so it no longer connects or detects any AP's and updateing to 4.0 didnt fix the problem.
have tyed the apple forums but apple just refuse to ack there is a problem.

props on the new JB.

Whoever is holding the phone to take screenshot, is holding it wrong. Only one bar...

haha. Was on a 3G only, but I still thought it was fitting.

ipod touch 3g (MC version) anyone get it to work?

Yep, just installed on my iPod 3rd gen MC model, Cydia is now on the home screen

Yeah, just did it to my wife's MC model. Works great!

Just used it on my iPhone 4 (IOS 4.0) and it seems to be working perfectly. Can still use MMS, it seems, do not know about facetime yet.

Reboot and check if MMS works.

This is a userland jailbreak and so (obviously) doesn't hacktivate. But apparently the proper jailbreak is coming soon

Any idea when proper jailbreak is going to come for 3GS? I have also read few articles about iOS4 draining the batteries of 3GS, few of my friends have installed the OS 4 version, they say when the backgrond apps like games ,WiFi is closed then there is no issue, is it true? Or is the OS really draining even if there are no apps running behind?

This has been fixed now and if you jailbrake it now you won't lose MMS or facetime. If you already jailbroke it before the fix was released, just run Cydia and let it upgrade.

I don't see this jailbreak lasting long myself, if the iPhone has an exploitable browser then the potential for abuse is great, anything could load itself on the phone with the right code, i.e a virus.
Having said that, it doesn't work on iOS 4.1 beta, so maybe it's already fixed and this is probably why they released the jailbreak now rather than holding it back for 4.1 like they intended.
