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.

I hope this helps!

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).

After all the trouble I had, I thought I would share with you how I installed it, and got XBMC to boot on load. I am using an ASUS AT3N7A-I  with a 1.6 dual core atom processor and NVidia ION chip set, 2GB of ram and a 80GB hard drive. So I will only be showing you how to use the NVidia drivers for Linux, but to be honest NVidia driver support for Linux is better than ATI support.

First, download the minimal install of Ubuntu Karmic Koala (12.1mb x86 12.2mb x64)

Download either the x86 or x64 version dependent on your hardware.

Once the disk image has downloaded either burn it to CD or use UNetbootin to boot from a USB pen drive.

Reboot the computer you wish to install xbmc on, and boot from the CD or USB pen drive, you may need to change some settings in your bios to boot from CD or USB.

Start the installation, and follow the onscreen instructions to set your language and keyboard layout. Enter a user name and password for your main account, for this I entered xbmc.

The installer will ask you what packages to install, scroll down to OpenSSH Server and press SPACE, then press ENTER to continue.

After the installation has completed, your computer will reboot.

When you get to the login screen, login with the user name and password you entered.

Once you have logged in we need to add the PPA for XBMC.

sudo nano /etc/apt/sources.list

And these lines to the end.


deb http://ppa.launchpad.net/nvidia-vdpau/ppa/ubuntu karmic main
deb-src http://ppa.launchpad.net/nvidia-vdpau/ppa/ubuntu karmic main
deb http://ppa.launchpad.net/team-xbmc/karmic-ppa/ubuntu karmic main
deb-src http://ppa.launchpad.net/team-xbmc/karmic-ppa/ubuntu karmic main


We will need to add the a key to aptitude to stop it complaining.

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 64234534 40618B66 CEC06767 318C7509 91E7EE5E

Sometimes the key server will return this error:
gpg: keyserver timed out
gpg: keyserver receive failed: keyserver error

A trick I found was to ping the key server address, after it responded try and run the previous command again:

ping keyserver.ubuntu.com

Now we need to update aptitude.

sudo apt-get update


Now we will install the NVidia drivers:

sudo apt-get install nvidia-glx-190

You will need to enter your password again.

Next, we want sound for our media, so we will install some sound drivers.

sudo apt-get install linux-sound-base alsa-base alsa-utils


Your user needs to be added to the sound group.

sudo usermod -a -G audio xbmc


Change xbmc to the username that you entered.

The sound level will be set to zero, to change the volumes we need to enter the sound mixer.

sudo alsamixer


Use you up and down keys and set the volumes to the maximum they will go. Press the right key until you get to IEC958, EC958 D, EC958 1 and press M on each of them to un-mute them.

Press ESC to quit out of the mixer.

To make alsa save the volumes run.

sudo alsactl store 0


Now we can install XBMC.

sudo apt-get install xbmc xbmc-skin-* xbmc-eventclients-* xbmc-scripts-*


This will install xbmc, all the skins and eventclients.

Now X will need to know about your monitor, so run:

sudo nvidia-xconfig

XBMC will need to control power settings of the computer:

sudo apt-get install pm-utils policykit


And give your user access to these power features:

sudo polkit-auth --user xbmc --grant org.freedesktop.hal.power-management.suspend
sudo polkit-auth --user xbmc --grant org.freedesktop.hal.power-management.hibernate
sudo polkit-auth --user xbmc --grant org.freedesktop.hal.power-management.reboot
sudo polkit-auth --user xbmc --grant org.freedesktop.hal.power-management.shutdown
sudo polkit-auth --user xbmc --grant org.freedesktop.hal.power-management.reboot-multiple-sessions
sudo polkit-auth --user xbmc --grant org.freedesktop.hal.power-management.shutdown-multiple-sessions


Again you will have have to change –user xbmc to the username that you entered in the installation.

Now the last thing to do is make XBMC launch at startup.

sudo nano /etc/init/tty1.conf


Change the line

exec /sbin/getty 38400 tty1


To

exec /bin/login -f xbmc < /dev/tty1 > /dev/tty1 2>&1

Next we need to get Ubuntu to clear the screen and start X:

nano ~/.bash_profile


And add these lines to the file:

case "`tty`" in
/dev/tty1) clear && startx &>/dev/null;;
esac


Now we need to tell X to start XBMC:

nano ~/.xsessionrc


Add the lines:

exec xbmc --standalone

This next step is OPTIONAL, to hide all the information about what is being loaded, we shall install a usplash boot screen.

sudo apt-get install usplash libusplash-dev usplash-theme-xbmc-*


Once the splash screen installation has completed we need to select a splash screen:

sudo update-alternatives --config usplash-artwork.so


Enter the number of the splash screen you wish to use, find examples below:

Pulsating Logo
Spinner Black
Spinner Blue
XBMC Logo

All the previews where created by DU-Duke

Next set the screen resolution of your tv in the usplash settings:

sudo nano /etc/usplash.conf


And add these lines:

resx=1920
resy=1080


My TV is 1080p, so the settings above will suite yours if it is full HD, for 720p enter:

resx=1280
resy=720


To make the new splash screen active run:

sudo update-initramfs -u

Now reboot your computer:

sudo reboot


When the computer restarts, you should see the splash screen you selected, and XBMC should boot up.

Now, go into XBMC’s Videos settings and select VDPAU for the render mode (if your graphics card supports it) and edit the Sound settings:

Audio Output: Digital
AC3: Off
DTS: Off
Audio Capable Device: plughw:hdmi
Passthrough Output Device: hdmi
Downmix: On


And that’s it, you should have a fully functional media centre running the latest version of Ubuntu and XBMC.

As this is an alpha version, you will need to perform some updates now and again until the final release is out.

To so this, ssh into your computer and update it:

ssh xbmc@your media centre IP
sudo apt-get upgrade


Now I can’t take all the credit for this, I have collected some information from other sources and put them together from here:

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.
