Simplest iPhone 3GS Untethered Jailbreak Released (any bootrom), Can be Unlocked with ease!

For a list of important Cydia apps and more screenshots, go here. Visit this page if you have an iPhone 4.

There is not much to write about this time around (no PC or Mac limitation)! Jailbreaking is perfectly legal btw!

All you have to do is :

– Make sure your iPhone is activated. It is not possible without a valid iPhone SIM. If you don’t have one, we must wait until another tool is released.

– Make sure you sync your iPhone to iTunes. This is important, just in case you know!

– If your iPhone is activated, you are 60 seconds away from a jailbreak. Connect to WiFi and launch Safari on your iPhone.

– Type in ‘jailbreakme.com’ in Safari and swipe the ‘slide to jailbreak’ button.

– Sit back and watch the fun! It should all be over in few seconds/minute depending on your WiFi connection!

– Now launch Cydia and choose ‘user’ when prompted to choose user type.

– Search for ultrasn0w [with a zero] and install it. Reboot your iPhone and enjoy a jailbroken, unlocked iPhone 3GS!

Known issues (from @comex’s tweets):

  • MMS/Facetime issues for some. You have to restore from backup to fix this issue. [This is now resolved! For those who are facing problems, update Cydia and reset network settings. For those who used it before the fix, chmod 755 /private/var/mobile/Library; chmod 755 /private/var/mobile/Library/Preference then Reset Network Settings should do]
  • T-Mobile MMS issues : Adding http://beta.leimobile.com/repo/ in Cydia and installing their package should fix MMS issues for T-Mobile users.
  • If it hangs in the middle of the process at the purple screen, reboot your iPhone and try again.

p.s : I tested this on an iPhone 3GS 4.0 with the latest bootrom.

    Feels strange when no custom firmware is required any more… 🙂 (for now at least)

      Yep, I am sure it will be blocked with 4.1 that is in beta already. Just like the last time!

    I have a jailbroken/unlocked 3GS on fw 3.1.2, using tethered jailbreak.
    So basically I can update my 3GS on iTunes to iOS 4.0.1 and then jailbreak/unlock with the described steps?

      Only if your iPhone is activated though. As long as you see the icons (homescreen), this will work.

    hello,

    While I was trying to unlock my iphone,something went wrong so I tried deleting the Cydia App and it did not work so I went ahead and restored my phone to factory settings. Now my phone is not switching on, it has an apple logo on the screen. I tried holding both home button and on/off button, it doesn't seem to work. Please help

      Make sure you turn your iPhone off and is disconnected from your computer. Now, while holding the home button, plug the iPhone back in. Now restore to stock iOS 4.0.1 and then jailbreak and unlock. You don't have to delete Cydia, just hide it. It is essential for unlock..

      Aww you bricked your iPhone. Basically its not going to work. If it dosent leave the apple logo and has a little loading circle and keeps restarting then you bricked it. Which means the software crashed and your iPhone is no longer able to be used. Take it to the Apple store and if they cant fix it then theyll replace it as long as there is no water damage to the phone. It happened to me a few months back with my 3G. they just replaced the phone cause iphone couldnt even recognize it.

      Goodluck.

      Unfortunately, there isn't a system in place to activate 4.0.2 iPhone 4 without the original SIM… We have to wait for more..

      jailbreakme.com won't work on 4.1 firmware. I am not aware of any other 'on phone' jailbreak. You need either a PC or Mac – it is simple and easy..

    I simply needed to thank you so much all over again. I do not know the things I might have tried without the actual suggestions contributed by you concerning my area. Completely was the fearsome concern for me personally, but finding out the very expert strategy you handled it made me to leap over contentment. I’m thankful for this advice as well as expect you know what a powerful job you happen to be providing educating many others thru your websites. I am certain you haven’t come across any of us.
