As many of you probably know, today Apple released a new firmware for the iPhone and iPod touch, iOS 4.1. If you are currently jailbroken and would like to keep your jailbreak, do not update! There is currently two known ways to jailbreak this firmware, one way would be through redsn0w, another and much more simplistic way, is through an updated version of jailbreakme.com. Right now we’re just waiting on Comex, creator of jailbreakme, to release the jailbreak(s). Here’s the newest post from the iPhone Dev-Team regarding iOS 4.1:
This time of year there are lots of new iPhone owners, and not everybody knows that accepting new iOS updates is the surest way to lose your jailbreak and/or unlock. While those of you who have Cydia or TinyUmbrella backups of your FW hashes will always be able to get back to 4.0.1 if you make this mistake, this doesn’t hold for unlockers. There’s currently no known way to revert your baseband — if you update your baseband you’ll lose the ultrasn0w unlock, possible forever.
Please stay away from this 4.1 release until a safe jailbreak procedure (which also preserves ultrasn0w) is developed and released.
P.S. There are a tiny number of iPhone3G owners who can revert their basebands due to a flaw in very early bootloaders…you will already know if you fit in this category!
Unlocking an iPhone allows one to use it with an unsupported wireless carrier, for example, T-Mobile, in the U.S. The iPhone Dev-Team has released an unlock for the iPhone 4 using the baseband 01.59. If you don’t know what baseband your iPhone is currently on, you can use a program by iH8sn0w, called f0recast for both Mac and PC. You can download it HERE.
This unlock is incredibly simple and fast. Here’s the steps:
If no signal is found, go to Settings and turn on Airplane Mode, then turn it off. If you still have no signal, reboot the iPhone. That’s it! Your iPhone 4 should now be successfully unlocked and using either T-Mobile or another unsupported carrier! Follow @TechGeec on Twitter for updates.
JailbreakMe 2.0 has now officially been released. This the new jailbreak for iPhone 4, iPhone 3GS, iPhone 3G, iPod touch 1G, iPod touch 2G, iPod touch 3G, and iPad on iOS 4, iOS 4.0.1, and iPad iOS 3.21 released by trusted member of the iPhone dev-team, Comex.
If you are planning to jailbreak, make sure you sync with iTunes first and create a backup just in case something happens to go wrong. Turn on your iPhone 4, iPhone 3GS, iPhone 3G, or iPad and open Safari. Then go to JailbreakMe.com. Slide “Slide to Jailbreak” bar to start the jailbreak process, and you will be given further instructions depending on what firmware your device is on.
This is currently the newest and easiest jailbreak for the iPhone and iPad. Also, many of you will be happy to know that jailbreaking is now 100% legal, but don’t forget that you will lose your warranty. Follow @TechGeec on Twitter for future updates.
Today, July 10, 2010, George Hotz (aka Geohot) released a blog post with proof that he has jailbroken the iPhone 4 with a program he’s made called limera1n. Currently, there has been no ETA. Here’s a picture for proof:
There has been so much confusion lately on which devices can be jailbroken, what programs to use, etc. Hopefully the video below will answer your questions. If you still have questions that weren’t answered in the video, leave a comment and your question will be answered ASAP.
On Monday, Apple released firmware 4.0 for the iPhone and iPod touch devices. This of course was a major upgrade.
As advised, you shouldn’t have upgraded your devices if you have previously relied on our tools for hacktivation and/or a carrier unlock.
With that said, today we are releasing PwnageTool 4.0
PLEASE READ THIS ENTIRE POST CAREFULLY, THERE ARE KNOWN UPGRADE TRAPS AND DIFFERENT UPGRADE SCENARIOS THAT NEED TO BE FULLY UNDERSTOOD AND CONSIDERED BEFORE USING THESE TOOLS.
Each supported device has few different scenarios that users need to consider when performing the upgrades, you need to check below and perform the upgrade in the particular way that matches your current device state.
NB: With PwnageTool 4.0 certain devices are not supported this is because they are not supported in iOS 4.0 or they are not supported by our software. We’re working on ways to get past these restrictions.
iPhone 2G - not supported
iPod Touch – not supported
iPod Touch 3G – not supported
PwnageTool 4.0 only recognizes the official IPSWs that came out yesterday. If you had developer access to the “4.0 GM” IPSWs, do not try to use those.
Summary: Currently, PwnageTool only works on previously jailbroken 3GS devices with the old bootrom.
If you have a Jailbroken iPhone 3GS with the OLD BOOTROM and you DID NOT use Spirit to jailbreak then you can create the ipsw with PwnageTool 4.0 and restore with your jailbroken recovery mode.
If you have an iPhone 3GS with the NEW BOOTROM this is NOT supported by PwnageTool 4.0
If you have a Jailbroken iPhone 3G at 3.1.2 (but not jailbroken with Spirit) then you should create the ipsw with PwnageTool 4.0 and restore from recovery mode or DFU mode.
If you have an out of the box iPhone 3G you should restore using a PwnageTool 4.0 ipsw using DFU mode.
If you have a Jailbroken 3.1.3 iPhone 3G it is very possible that this can fail from recovery mode, if this failure happens you will need to restore using DFU mode.
As an alternative to PwnageTool, you can use redsn0w on iPhone 3G (on both Windows and Mac) as mentioned in our last post.
IMPORTANT! Whenever you need to enter DFU mode, you will need to do so using PwnageTool.
iPod touch 2G
If you have an iPod touch 2G (non-MC model) that is jailbroken (but not with Spirit) then you can restore using recovery mode.
As an alternative to PwnageTool, you can use redsn0w on non-MC iPod Touch 2G (on both Windows and Mac) as mentioned in our last post.
As you probably know by now, ultrasn0w has been updated to cover all basebands from 04.26.08 onward. Many thanks to @sherif_hashim for finding the crashing command that the new ultrasn0w 0.93 uses! He worked hard at finding the crash, and he kept it confidential until the right time to use it.
iPhone 3G and 3GS baseband unlockers (those who rely on ultrasn0w to make phone calls) should always be very wary to update their firmware, however our Ultrasn0w application will unlock all recent (including the current) 3GS and 3G baseband firmware versions. Once you are jailbroken using PwnageTool 4.0, install ultrasn0w from Cydia and you’ll be unlocked.
Remember! This baseband unlock situation is rare, should you upgrade your iPhone blindly at the next iOS release please don’t expect an unlock – but for now you are OK (whatever state your baseband is in).

2. Connect your device to your computer and shut it off (slide to shut down)
3. Download the corresponding iOS 4 firmware for your iDevice from the “Downloads” section of TechGeec.com
4. Open Redsn0w and browse for the firmware that you downloaded. Select “Next”
5. Select which features you’d like to be installed with the jailbreak (certain devices cannot have multitasking, homescreen wallpaper, or battery percentage so enabling those features gives that device the features)
6. Click “Next” twice and prepare to put your iDevice into DFU Mode
7. On the screen that shows you what to do to put your device in Recovery Mode:
Hold power button for 3 seconds
While still holding the power button, hold the home button for 10 seconds
While still holding the home button, release the power button and continue holding the home button for 30 seconds
8. Congratulations! Once your device reboots you should have Cydia on your home screen.
Feel free to leave a comment below stating what your favorite feature of iOS 4 is, if you enjoy jailbreaking, if you’ve had any problems, or any other sort of feedback, and please, share this post and TechGeec.com with your friends.
