These instructions will walk you through jailbreaking your iPhone on your PC using the Dev-Teams official Redsn0w software for Windows. This will not jailbreak the new iPhone 3G S. Redsn0w is also available for Mac (Intel only) You can follow the same instructions.  I used Redsn0w on a Vista PC but it should work with XP as well.

Use Redsn0w to:

• Jailbreak and unlock OG iPhone
• Jailbreak iPhone 3G
• Jailbreak iPod Touch 1st Gen
• Jailbreak iPod Touch 2nd Gen

To begin, you will need to download the following: (all downloads require login)

• Redsn0w for Windows: Redsn0w for Windows (4377)
  
• Redsn0w for Mac (Intel only): Redsn0w for Mac OS X official torrent
• Official firmware for your device: iPhone OG 3.0 restore firmware .ipsw (1772)
• Bootloaders (Only if unlocking): iPhone 3.9 Bootloader (1234) iPhone 4.6 Bootloader (788)

Save these to your desktop for easy access.

1. Make sure you have updated your device officially to OS 3.0 through iTunes.

2. Make sure your iPhone is off.  Do this by holding the power button (top of phone) then slide to power off.

3. Connect your iPhone via USB.

4. Start Redsn0w.exe

5. Browse for your firmware that you downloaded. (Make sure you have the correct firmware for your device) Then click next.

6. If you want to unlock your OG iPhone then check both Cydia and Unlock.  If you do not need to Unlock then only have Cydia checked and proceed to step 7.

6 a. If you are unlocking your iPhone then you need to browse for the 3.9 and 4.6 Bootloaders that you should have downloaded and saved.  Then click next.

7. Redsn0w will ask you to make sure your iPhone is powered off but you should have done that already.  If you didn’t follow the directions to do it now.

8. Once your iPhone is off, be prepared for step 8 because it starts quickly, then click next.

9. This is where you will put your iPhone into DFU mode.  Follow the instructions in order to achieve this.

10. If you correctly put your iPhone into DFU mode you will see that Redsn0w will begin the jailbreak process.  Let it do it’s thing, which should take about 5 minutes.  (Redsn0w crashed the first time I tried to jailbreak and left me with the “Running PwnApple” on my phone.  Don’t worry, just power off your phone again and start the process from the beginning.  It worked perfectly the 2nd time for me.)

Redsn0w gives you instructions through the entire process so you should not have any problems as long as you follow everything exactly.  If you have any problems please leave a comment so we can help.

If you feel like it’s worth it

Yesterday the iPhone Dev-Team only released Pwnage tool for Mac OS X which left many PC users begging for them to release QuickPwn for Windows.  They have now released the Windows version of their jailbreak software code named Redsnow.  Redsnow previously was the name of their iPod Touch 2nd Gen jailbreak, but this morning they have re-released it to also include the OG iPhone, 3G iPhone, and both versions of the iPod Touch; this will not jailbreak the new iPhone 3G S.  Redsnow provides similar function as QuickPwn and is available for Mac or PC.  If you want to build a custom firmware, use Pwnage tool, but that is only available for Mac at the moment.  If you have a 3G using Yellowsnow to unlock and want to stay unlocked, do not use Redsnow, you want to wait for the release of Ultrasnow that will be available through Cydia soon.

Check back soon for a full walk-through on how to jailbreak your iPhone using Redsnow.

As always, use this software at your own risk.  Make sure you read all instructions and warnings.

The iPhone Dev-Team have officially released their Pwnage Tool application for jailbreaking the iPhone OG, iPhone 3G, and iPod Touch 1st Gen running OS 3.0.  This release is only for use on a Mac running OS X.  A similar tool, QuickPwn for Mac and PC, will be released very soon.  As always you are cautioned to use this at your own risk as it may void your warranty and if you don’t follow directions well then you may want to find someone who can because you could bork up your device.  Here is the release straight from the iPhone Dev-Team blog.  Make sure you read the entire post to make sure your device is supported.  There are certain restrictions if your phone is unlocked and if you have an iPod Touch 2nd Gen.  Download links for the Pwnage Tool are included.

Happy Jailbreaking
iPhone Dev-Team

The iPhone Dev-Team has been working hard to bring us jailbreak software for the iPhone and iPod Touch and their latest versions of Pwnage Tool and QuickPwn are on the verge of being released.  There are still a few bugs they are trying to work out before they release, but it should not take them that long.  In the meantime, they may release a version that still has a bug that disables the YouTube app on devices that are not legally activated with AT&T, seeing that it will only affect iPhones that are unlocked.

Update 1 (Wednesday morning):

• Only ultrasn0w is going to take til Friday to get pushed out.  All of our other tools should be out pretty soon after the official Apple release.
• If you apply our jailbreak when it comes out, you can install ultrasn0w anytime after that.  You obviously won’t have cell service in the meantime, though.
• This may in fact be directly applicable to the iPhone 3GS if it can be jailbroken, because it runs the same baseband version.  Whether or not it can be jailbroken is a big question right now!
• If you’re on Twitter, please give @Oranav a pat on the back.  He could have revealed the crash he found to Apple and maybe gotten quite an incentive in return. Instead, he told us about it so that we could work it into an injection vector for the soft unlock.

Update 2 (Thursday morning):

• We have two issues that we’ve been trying to resolve:

1. There are new 3.0 complications with YouTube.app if you’re on a hacktivated (unofficially activated) device
2. There’s a bug in Apple’s new version of asr that our custom IPSW’s are tickling and causing crashes on, on some devices.  (For the nerdy or curious among us, the details of that bug were tweeted by planetbeing a month ago.)

• As of Thursday morning we now have a workaround for #2.  For #1, we’ll try our best to get it fixed but we may end up releasing a preliminary jailbreak in which YouTube doesn’t work for hacktivated devices, and then follow that up with a more complete jailbreak when we can.

iPhone Dev-Team

The iPhone Dev Team has released, on their blog, that they have successfully ported their Yellowsnow carrier unlock to work with the upcoming Apple release of iPhone OS 3.0. The Yellowsnow unlock was developed for the 3G iPhone when OS 2.0 was released. Many users were hoping for this because if you had been using an iPhone 3G on a carrier, other then AT&T, you would not be able to take advantage of the new functionality in the much anticipated 3.0 update, without losing their call function. No worries now apparently; the Dev Team says they will showcase their official/unofficial Yellowsnow Ultrasnow unlock today via a live feed. A member of the Dev Team, MuscleNerd, will twitter the live feed link later this afternoon. If you want to see this first hand make sure you follow @MuscleNerd on Twitter.

I have been locked to AT&T since the release of the OG iPhone and have had no need to use the Yellowsnow unlock, but apparently many have. I have never seen the reason for unlocking the iPhone when AT&T forces your to sign a 2 year contract. Unlocking the iPhone only makes sense if you purchase your iPhone from the plethora sold on Ebay and Craigslist, which apparently a great number of you do.

The Dev Team has also eluded that they are ready to work on an unlock solution for the soon to be released iPhone 3GS. They don’t want you to ask them about it. If they told you, they would have to kill you.

P.S. For the new iPhone 3GS, please don’t expect periodic updates about any progress we have or don’t have. Nothing gives Apple the upper hand like someone tweeting or blogging partial hack results. That’s not how cat & mouse is played That’s how the cat gets fed.

UPDATE:  The Dev team have changed the name of the unlock to Ultrasnow.  Pointing out that the new soft unlock with work with all basebands as long as you are on FW 3.0

iPhone Dev-Team

Some very crafty crackers have figured out a way to circumvent Apple.com in order to purchase the new iPhone 3GS and have it delivered right to your house on July 19th, with free shipping to boot.  The process involves getting an add on for Firefox and using a little click and trick. This process does not allow you to get the subsidized price but it does let you skip right by having to sign up for a 2 year AT&T contract.  Note that this is still a carrier locked phone, but in theory you would be able to go month to month with your plan.  You can fully process your order including charging your card but I wonder if the Empire AT&T will figure out what is going on and get your orders canceled if they see there is not a contract associated with the sale.  You can find full instructions at iTalkiPhone.com

I don’t condone any of these actions but I’m really interested to hear how it goes if someone not related to Rotilda decides to try.  Strictly for information purposes.  If you try this, come back and leave a comment on how it worked.
