As of today the A5 processor devices (iPhone4S/iPad2) untethered jailbreak is finally available for iOS 5.0.x.
Get more info on Greenpois0n.com or download the windows software directly here.
RgdsNOTE: Because Absinthe creates a backup and restores it onto your device as part of the way it gets files on the device, we recommend the device is mostly empty when you start the process. To do this, CREATE A BACKUP IN ITUNES FIRST (connect to iTunes and sync). If you're using iCloud to backup, go to Settings > iCloud > Storage and Backup > Backup Now.
ONLY ONCE YOU'VE BACKED UP, on your device go to Settings > General > Reset > Erase All Content and Settings. MAKE SURE YOU'VE BACKED UP YOUR CONTENT. You do not have to Erase All Content and Settings if you don't want to, but the jailbreak could take up to 20-30 minutes to complete if you don't, depending on what's on your device.
Alright, let's get started. First thing you'll need to do is download the Mac version of Absinthe 0.2 from mod.my/absinthemac02, or the Windows version from mod.my/absinthewin02. Double-click the zip file to unzip it if your browser didn't automatically unzip the file.
Making sure your device is connected, double-click Absinthe to launch it. You will see the Absinthe home screen, and Absinthe should tell you your device (and firmware version) is detected. Press the Jailbreak button.
Absinthe will then go through a few status messages while it jailbreaks your device. It will stop for a bit at Waiting for reboot - not done yet, don't unplug your device yet!, and once the device has finished rebooting it will continue the jailbreak. Do not touch or unplug the device during this process.
Once the process has finished in Absinthe, it will alert you to unlock the screen if necessary and tap the "Absinthe" icon to finish the jailbreak. Remember, the icon may not be on the first page - scroll to find it.
Tapping the icon will bring up a webview with a white page, and then your device will restart.
NOTE: If you see an "Error establishing a database connection" error, please go to Settings and turn on VPN, and wait instead. The VPN connection will give an error. This is normal. A reboot should happen a few moments after the error.
You will see the Apple logo with a progress bar quickly as the device restarts, and then your device will power back on.
NOTE: The Set Up iPhone (or iPad) GUI you see when you restore an iDevice will now appear. If you backed up with iCloud at the beginning of this tutorial, please choose Restore from iCloud Backup in the Set Up iPhone GUI, and restore from the backup you took at the beginning of this guide.
The iDevice will then restore from backup, reboot, and you're good to go.
Cydia is now on your device where the Absinthe icon was before!
