It’s finally available, and over the air too! No need to use a computer. I have jailbroke at least a dozen phones today (08/01/2010) and haven’t had an issue with MMS or FaceTime.

jailbreakme.com is back!

Thanks to some serious work by @comex, you can now jailbreak your iPhone, iPod Touch, or iPad right from MobileSafari — no PC or Mac needed!

Just visit http://jailbreakme.com on your device.

For those needing a carrier unlock, use the existing ultrasn0w in Cydia on your iPhone3G or iPhone3GS.  After a short testing period, we’ll push out the iPhone4 version.

Note: The earlier MMS and Facetime issues have been fixed.  If you already ran the version with those problems, launch Cydia and accept its offer to update.

After messing around with my 3GS and the 4.0GM I was attempting to do the Jailbreak that’s mentioned on my site as well as others. After the restore process I always got an error 16XX but, after messing around a bit I found that if I restored to 3.1.2 Official firmware, then I used Pwnage Tool to 24kpwn then I was able to restore directly to my iOS 4.0GM Jailbroke firmware and no longer had the errors.

I hope this helps!

MSFT.guy released iPhone 3GS iOS 4 pwnage tool bundle, means with a little workaround in pwnage tool you can update your already pwned iPhone 3GS to iOS 4 GM with jailbreak and unlock support. Procedure is very easy, you have to add two bundle files to the DevTeam’s pwnage tool for Mac, that will enable support for custom firmware 4 beta Creation. Need less to say iOS is still in GM build, final build is now less than two weeks away.

Note / Warning :

• The bundles included in this release are not official because they were not issued by the DevTeam.
• You must be on already pwned 4.0 Beta / 3.1.3 / lower.
• iPhone 3GS and Mac OS only.
• This is for advanced users only if you don’t know, what you are doing stay away and wait for official Dev team / Geohot tools.
• Use this guide on your own risk, i am not responsible for any damage (if any). The procedure mentioned below is tested by me and it works.

Requirements:

• Pwnage Tool 3.1.5
• iPhone2,1_4.0_8A293_bundle
• data

Instructions to add custom bundles

1. Download the iPhone 3GS iOS 4 GM Bundle mentioned in the requirements and unzip to your desktop or where ever you want .

2. Right-click the Mouse on PwnageTool and click on “Show Package Contents”

3. Then enter “Contents” then “Resources” and finally “FirmwareBundles”.

4. Move the iPhone2,1_4.0_8A293_bundle.zip to the FirmwareBundles folder  and close the folder.

Instructions to Update Cydia in pwnage tool

1. move pwnage tool.app to desktop

2. Place data.tar in PwnageTool.app/Contents/Resources/CustomPackages/CydiaInstaller.bundle/files/

3. and then open terminal and perform following commands

cd desktop

cd PwnageTool.app/Contents/Resources/CustomPackages/CydiaInstaller.bundle/files/

tar xpvf data.tar

4. Launch PwnageTool (now supported for iOS 4 GM) and proceed normally with the construction of custom firmware, you can take a reference fro our previous guide to Jailbreak iPhone With Pwnage Tool (Mac). This way, Mac users can jailbreak the latest iOS 4 GM while preserving their baseband.

So you upgraded to the iPhone 4.0 beta and possibly like me you quickly came to regret it because some of your favorite applications just aren’t working right (for me it was Reeder and iSteamy). Well, how do you go about the process of getting back to 3.1.3? Well, it’s pretty simple actually. Here’s what I did and what may help you as well.

First, put your iPhone into DFU mode. At this point if you’ve done it properly iTunes will start bouncing in your dock and complaining about finding an iPhone in Restore mode and it can’t be used until you restore it. So, do that. Click restore and the iPhone 3.1.3 firmware will be put onto the phone. But, just when you think all is well, you’re going to get a nasty 1055 error stating that the firmware couldn’t be restored. Don’t worry. This is normal.

Now, you could go through the hassle of going back to 3.1.2 using the keys on Saurik’s server (you have stored your keys there right?)… then using a jailbreak to get back to 3.1.3 but there’s a much easier way. Go to iHackintosh and download a little utility called iRecovery. Once you have iRecovery downloaded, open up a terminal window and type the following:

cd /directory/to/iRecovery then type iRecovery -s

Wait for iRecovery to load then run the following commands one at a time:

setenv auto-boot true
saveenv
/exit

Reboot your phone by holding the home and power button for about 10 seconds, the phone will then reboot, connect to iTunes and activate.
You’re done!

EDIT: So, here’s another few key steps it looks like you’re going to need if you intend to be able to jailbreak 3.1.3 again. I ended up having to downgrade to 3.1.2 – You HAVE to have saved the ECID file with Saurik. Edit your host file (see details here) to include the following:

74.208.105.171 gs.apple.com

With that in place in the host file and your ECID on Saurik’s server you can safely downgrade to 3.1.2. Once the downgrade was done, I immediately loaded up the Pwnage tool, had it build a custom 3.1.3 IPSW and followed the steps to get into recovery mode. Once 3.1.2 was in recovery mode, I switched back over to iTunes and installed the 3.1.3 IPSW. I’m now back on 3.1.3 fully jailbroken and since 4.0 wasn’t able to backup the iPhone properly – I’m even able to restore the phone from the 3.1.3 backup i took yesterday! Huzzah!

(Don’t forget to return your host file to normal when you’re done with all the IPSW tango).

Apple has released a new version of iTunes, iTunes 9.1 which changes how certain things work. If you have upgraded to iTunes 9.1, several programs will start giving you an error that ASL.dll is missing.

This problem also occurs while trying to jailbreak your iPhone while using Blackra1n, when running the executable will give you an error saying that ASL.dll is missing as shown in the above screenshot.

The solution for this is simple, you will need to place the Blackra1n executables in the Apple folder under Common files in Program Files. The folder would be located in the following locations:

32 Bit – C:\Program Files\Common Files\Apple\Apple Application Support

64 Bit – C:\Program Files (x86)\Common Files\Apple\Apple Application Support

Once you copy the blackra1n executable to the above folder, create a shortcut for it on the desktop and double-click it to run it as usual.
