Update: The iPhone Dev Team have updated Redsn0w to 0.7.2 - Download the newest version from our iPhone Downloads section:
redsn0w 0.7.2 for Mac OS X download
redsn0w 0.7.2 for Windows download

iPhone Dev Team has released an application that works similar to quickpwn and provides similar functionality. Redsn0w is an easy to use, multi-platform, multi-device jailbreaking and unlocking (iPhone 2G only) tool for the iPhone 2G (original iPhone), the iPhone 3G (but not the 3GS) and also the iPod touch (first and second generation). Luckily for Windows users, who couldn’t use PwnageTool, Redsn0w is available for both Windows and Mac OS X users. However, iPhone Dev Team notes that there are some issues using redsn0w with OS X PPC and they suggest you use an Intel Mac till these issues are resolved.

1. GOLDEN RULE: If you are using a 3G iPhone with yellowsn0w and rely on yellowsn0w to obtain cellular service, then you should NOT use redsn0w right now. Ultrasn0w (the 3G carrier unlock) is not included with this release and therefore your baseband will be locked and unable to use an operator other than the official one it was bought for. UltraSn0w will be released via APT (cydia and icy) soon. If you have an original iPhone (1st generation) then 3.0 carrier unlock works with this redsn0w release.
2. Yellowsn0w in its current form will NOT work with the baseband version that is present in the 3.0 update, you will need Ultrasn0w, which will be released sometime soon, Ultrasn0w will work with all iPhone 3G models (but not 3GS), even ones that were previously unlockable, Ultrasn0w (when available) will be released via APT (this means you will be able to get it via Cydia or Icy).
3. Please read all parts of this post before downloading and using these tools.
4. Read items 1, 2 and 3 again and again.
5. This app is suitable for the recent 3.0 release
6. redsn0w will NOT work for the iPhone 3GS.
7. redsn0w WILL work for Original iPhone (1st Generation), Original iPod touch, iPod touch 2G and the iPhone 3G (not the iPhone 3GS).

Redsn0w is easy to use, simply upgrade the device in iTunes to firmware version 3.0 and run redsn0w to activate and jailbreak the device (and if you are using an original iPhone 2G, it will unlock it too!)

*Note*: there are some issues using redsn0w with OS X PPC, please use an Intel Mac while the iPhone Dev Team fixes these issues

Please note, this is Mac OS X Only.

Digg It!

It’s update day! The iPhone Dev Team has released it’s latest version of QuickPwn for Windows coupled with poorlad’s improved QuickPwn GUI. This update is labeled ‘150′. Mac user’s you haven’t been forgotten the dev team plans to release an update to PwnageTool today as well. We will make sure to bring that to as soon as it is released.

QuickPwn Windows doesn’t work well with virtualization as there are some problems with the way USB resets are handled, so we wouldn’t advise trying it, we have had reports of some success with VMWare Fusion 2.0 Beta 2, but this shouldn’t be relied on, use PwnageTool instead, or wait for QuickPwn Mac.

QuickPwn for Mac is being tested right now by a group of testers and we’ll release this when it is ready for public beta (this won’t be within the next 24 hours, but should be within the next week).

There are no significant updates with regard to the 3G baseband unlock, most of us have been busy with real life, when we get any further we’ll let you know.

Download QuickPwn RC3 from our iPhone Downloads Section.

The iphone-dev team has released PwnageTool 2.0.1 for folks who experienced problems with the earlier version.

PwnageTool 2.0.1 changes:

• It auto-finds the bl39 and bl46 files better, if they’re on your computer
• It creates the ~/Library/iTunes/Device Support/ folder if not present, which should help with some 1600 errors people have been having.
• Many people have reported the PwnageTool not starting up at all (the icon never stops bouncing). This issue should be resolved now.
• The Sparkle AppCast URL is fixed in this version, so automatic updates should work for future releases.

It’s been released early! The iPhone Dev Team’s PwnageTool 2.0 is out! We’ve got it in our iPhone Downloads section under iPhone Utilities or simply click here to download it.

We are testing it out on both the iPhone EDGE & iPhone 3G and will have a full review our Pwning fun soon.

Files you may need to go with PwnageTool 2.0:
iPhone Firmware 2.0 for EDGE
iPhone Firmware 2.0 for 3G
iPhone BootLoaders 3.9 & 4.6

Don’t have a Mac? If you are using an iPhone EDGE with Windows you can try using iTunes to install the PwnageTool 2.0 custom firmware I created.

From the team:

We’ll be releasing a more official announcement soon, but we wanted to get the tool out there. We sincerely hope you enjoy using it as much as we enjoyed making it :)

Update: Just to clear up some confusion over what this actually does: yes, it jailbreaks and unlocks older iPhones, and jailbreaks iPhone 3Gs and iPod Touches. We only support the 2.0 firmwares.

Update: If you get Error 1600 from iTunes, try: mkdir “~/Library/iTunes/Device Support” ; if that directory already exists, remove any files in it. Then re-run PwnageTool.

Update: If DFU restores are giving you trouble, another route to pwned 2.0 for 1G owners is to use our first pwnage at 1.1.4. Once you are pwned there, you can do a normal recovery-mode restore to your custom 2.0 ipsw. BTW the iPhone does *not* need to be pre-pwned to be able to DFU-restore into a pwned ipsw — it needs to be pre-pwned only for normal recovery-mode restores of custom ipsw’s.

Update: Mail application not working at 2.0? Please restore to your custom ipsw (you don’t need to DFU restore if you are pwned, normal restore will work now too) but then select “Set up as a new iPhone” when iTunes asks. Your first sync will bring back all of your settings anyway.
