Update #2: After following Marc’s advise in the comments below, turning OFF Pop-up blocker on Safari helped my issue with using Jailbreakme 2.0 Star on my iPad WiFi+3G. I also did the following:

• Cleared cache and cookies in Settings -> Safari
• I also turned OFF “Block Pop-ups” Settings -> Safari as per Marc’s advise
• Rebooted

If nothing seems to be working for you. Try using http://jailbreakme.modmyi.com/ or http://www.jailbreakme.com/ — Exactly as shown there.

Let us know how it works out for you!

iPhone Dev Team’s member, Comex, has released a stunning new jailbreak for, apparently, all iOS devices and it’s all performed via Mobile Safari with JailBreakMe 2.0 star — Yup, just like the old days.

To jailbreak with JailbreakMe:

1. Head over to http://www.jailbreakme.com on your iOS device
2. Slide to jailbreak on the screen
3. Mobile Safari will download some stuff
4. Then, the jailbreak process will begin
5. Don’t panic, jailbreak process will take a while
6. Once it’s done, you’ll get a confirmation notice and Cydia will now be on your home screen!

I can verify it works on an iPhone 4 running iOS 4.0 — 9to5mac verified it worked an iPad and iPhone 4 running 4.0.1 — this will NOT work on iOS devices running iOS 4.1 beta.

Note: Please make sure you back up your stuff before you attempt this. You can never be too safe. Use strictly at your own risk — Sure it worked for me, but it can fail for you or someone else.

The EFF (Electronic Frontier Foundation) has issued a press release announcing the government’s policy changes that came at the request of the EFF and has posted the full document issued by the Copyright Office of the U.S. Library of Congress.

On balance, the Register concludes that when one jailbreaks a smartphone in order to make the operating system on that phone interoperable with an independently created application that has not been approved by the maker of the smartphone or the maker of its operating system, the modifications that are made purely for the purpose of such interoperability are fair uses. Case law and Congressional enactments reflect a judgment that interoperability is favored. The Register also finds that designating a class of works that would permit jailbreaking for purposes of interoperability will not adversely affect the market for or value of the copyrighted works to the copyright owner.

Also, the U.S. Library of Congress stated that copyright concerns can not be used to prohibit unlocking of mobile phones under the Digital Millennium Copyright Act (DMCA). However, carriers can continue to prevent unlocking in many circumstances and can also pursue cases against individuals by citing breach of contract under the carriers’ ToS (Terms of Service).

Redsn0w is iPhone Dev Team’s tool to jailbreak iOS (iPhone OS). Much like iPhone Dev Team’s PwnageTool or ih8sn0w’s sn0wbreeze, both which can jailbreak iOS4 as well. Redsn0w is both for Mac OS X and Windows PC.

This is a beta release of redsn0w. It uses the same pwnage2 DFU-mode exploit that we’ve been using since the 2.x days. Nothing new is revealed to Apple, and it’s not applicable to the iPad.

This beta release supports:

• iPhone 3G and iPod touch 2G only (for now)
• Mac OSX x86 and Windows only (for now)
• the 4.0 official FW only (for now)

If you’ve already updated your device to 4.0, the next steps are:

1. Make sure you’ve already activated your iPhone3G or iPod Touch 2G with iTunes
2. Launch the beta redsn0w 0.9.5b5
3. Select your stock 4.0 ipsw (you’ve already used this to update your device to 4.0)
4. Select “Install Cydia” and click “Next”. Use DFU mode to install the jailbreak.
5. When your device comes back up, you’ll notice Cydia has a blank white icon Allow Cydia to reorganize, then accept the update it offers. When Cydia restarts, you should see its real logo now.

This is BETA software and many things may go wrong, use strictly at your own risk!

Sorry for the delay, I somehow missed this. Anyway, the iPhone Dev Team have updated their jailbreaking tool, PwnageTool, to jailbreak the latest and greatest, iOS 4.

Remember, PwnageTool is Mac OS X only.

Since iOS 4 isn’t compatible with a number of Apple devices, these devices are not compatible with PwnageTool v4.0.1:

• IPhone 2G – not supported
• iPod Touch – not supported
• iPod Touch 3G – not supported

iPhone 3GS:
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 4.0.1 and restore with your jailbroken recovery mode. 
• If you have an iPhone 3GS with the NEW BOOTROM this is NOT supported by PwnageTool 4.01

iPhone 3G:

• If you have a Jailbroken iPhone 3G at 3.1.2 (but not jailbroken with Spirit) then you should create the ipsw with PwnageTool 4.01 and restore from recovery mode or DFU mode.
• If you have an out of the box iPhone 3G you should restore using a PwnageTool 4.01 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.

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).

Baseband Unlock:

• 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.
• Major props to @oranav (who found the earlier +xlog crash).  He also had this crashing command! 
• 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 4.01, 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).

Now that you know what devices to use PwnageTool 4.0.1 with, start jailbreaking iOS4 and enjoy the iPhone Hacks!

There’s nothing wrong with your eyes. iPhone 4 has been jailbroken. MuscleNerd, member of iPhone Dev Team, posted a picture of Cydia running on an iPhone 4.

Planetbeing posted this on Twitter:

Think I’m the first one I know about to get a root shell (and SSH) on iPhone 4, using poor @comex’s code (since he has no iPhone 4)

Then MuscleNerd followed up with:

Congrats to @comex for another userland JB http://is.gd/d5N6I <-- hi-res Cydia via @planetbeing & @chpwn iPhone4s

Planetbeing made it clear that the release of this jailbreak is not known at this time; probably not anytime soon.

Don’t want to speak for @comex, but afaik no one has breathed a word about release date and what we have right now is nowhere ready.

Stay tuned!

Awesome! Those of you that’ve been waiting for a Jailbreak for the iPad and an untethered jailbreak for the iPhone and iPod Touch — it’s here — no more waiting on Geohot. That’s right — Spirit is here to satisfy those needs. Spirit jailbreaks all current devices: iPad, iPhone, and iPod Touch on firmwares 3.1.2, 3.1.3, or 3.2. Spirit, however, is not a carrier unlock tool — it only jailbreaks said devices.

Requirements

• Any iPad, iPhone, or iPod touch on firmware 3.1.2, 3.1.3, or 3.2.
• An activated device: one not stuck on the Connect to iTunes or Emergency Call screen.
• Any version of iTunes 9 (including 9.1.1).
• Syncing with iTunes before trying this highly recommended.

Note: On iPad, all this is still sort of beta. Some packages in Cydia, not designed for iPad, might screw up your system and require you to restore. Be careful.

That’s right, an untethered jailbreak for your iPod Touch or iPhone device. GeoHot, has posted a video demonstrating an iPhone that is jailbroken and rebooting it to demonstrate that it really, in fact, is still jailbroken.

The jailbreak is all software based, and is as simple to use as blackra1n. It is completely untethered, works on all current tethered models(ipt2, 3gs, ipt3), and will probably work on iPad too.

There is, currently, no due date for this software.

Stay tuned!

The iH8sn0w Dev Team have released sn0wbreeze version 1.5.1 to jailbreak and unlock Apple’s recently released iPhone OS 3.1.3. Sn0wbreeze allows users to upgrade from a jailbroken iPhone OS 3.1.2 or lower to iPhone OS 3.1.3. We encourage you to carefully read below before attempting to use this application.

sn0wbreeze is a tool for Windows that will jailbreak your iPods and iPhones, setup custom boot logos, activate your iPhone, root partition size, build custom IPSW, and more!

Alright, so it all seems fine and dandy so far but here’s the catch: Your iPhone or iPod MUST BE iPhone OS 3.1.2 or lower and it must be jailbroken or pwned prior to using sn0wbreeze. Sn0wbreeze will NOT work if you have already upgraded to iPhone OS 3.1.3. It allows users to upgrade their jailbroken iPhone runing iPhone OS 3.1.2 or lower to jailbroken iPhone OS 3.1.3.

Sn0wbreeze will work with the following devices:

• iPhone 3GS (OLD BOOTROM ONLY. If the 4th/5th digits of the serial # are before 40 then you should have the old bootrom. If your current jailbreak is tethered DO NOT try this.)
• iPhone 3G
• iPhone 2G
• iPod Touch 2G (OLD BOOTROM ONLY. If your current jailbreak is tethered you have the new bootrom so stay away and/or If your model # starts with MC you have the new bootrom so stay away!)
• iPod Touch 1G

In addition, sn0wbreeze can unlock these following devices:

• All iPhone 2G
• iPhones with 04.26.08 Baseband
• iPhones with 05.11.07 Baseband

Note: You can find your baseband/firmware via the Settings app (General->About->Modem Firmware

Apple released iPhone OS 3.1.3 recently to improve and fix a few issues with iPhone OS 3.1.2 and the iPhone Dev Team recently released their updated redsn0w software to jailbreak iPhone OS 3.1.2 but an unofficial feature of Redsn0w 0.9.2 is the ability to also jailbreak iPhone OS 3.1.3. That said, lets get jailbreaking that device of yours.

In this tutorial, I will show you how to jailbreak iPhone OS 3.1.3 in the same way you would jailbreak iPhone OS 3.0 with redsn0w 0.9.2.

Please follow these instructions clearly and you’ll be a-o-k. Now, before we begin you may notice that we use the iPhone OS 3.1.2 IPSW to jailbreak our iPhone OS 3.1.3 device, this is no mistake. When you get asked to select the iPhone firmware you have installed then choose the iPhone OS 3.1.2 IPSW. Please make sure you have updated your device to 3.1.3 by either updating officially via iTunes or restoring via iTunes. Keep in mind that restoring your iPhone will erase your iPhone’s content. In this tutorial we use Redsn0w version 0.9.2

Note: We are not responsible if your device blows up in the middle of the jailbreak process or if your device doesn’t turn on after using this. Use, strictly, at your own risk!

1. First is first, download redsn0w 0.9.2 here (for Windows) or here (for Mac OS X)
2. Second, Download iPhone OS 3.1.2 (to Jailbreak 3.1.3) or whatever firmware you’ll be using to jailbreak – here
