The iPhone Dev-Team has released a beta of their 'backup plan' untethered jailbreak. Currently the beta is only for Mac users and is limited to iPhone4, iPad, and iPod touch 4G.
Important Points:
● This is a beta tester program. Things can go very wrong, so please don’t even consider testing if you have pictures or other media on your device that you haven’t backed up!
● For the same reason, please don’t participate if you rely on the ultrasn0w carrier unlock. Wait for the final version!
● Until we fix some sandbox issues with bluetooth, the bluetooth functionality is disabled.
● This very first beta1 is limited to iPhone4, iPad, and iPod touch 4G.
● You must already have the usbmuxd software installed and running on your Mac.
You can download the updated version of RedSn0w here. We will be posting our tutorial shortly!
