Jailbreak iOS 5 With Redsn0w 0.9.9b4 [ Download ]

Well, iPhone Dev-team has brought good news for iOS 5 users, he has updated redsn0w to redsn0w 0.9.9b4. This update is rich with new updates and improvements . You will find full guide for installing redsn0w 0.9.9b4 below and the new features and improvements after this jump.

Update #12: For those of you who experiment with your own custom ramdisks using the -r command-line option, version 0.9.9b4 adds auto-detection support for iOS5. This is needed because iOS4 and iOS5 treat the root partition differently (it’s encrypted in iOS5). redsn0w will now upload the correct iOS5 kernel by itself, but it’s up to your own launchd to determine if it needs to mount using the old or new partition scheme.

redsn0w now also accepts both native and img3-encapsulated versions of files you provide via the -r, -k, and -d command-line options (do redsn0w -h to show all the available options).

You can use this tutorial we posted before and follow the instructions to install Redsn0w.

Important Notes:

• This is an tethered jailbreak which means that you will need to jailbreak your device every time you reboot your device.
• This new update of Redsn0w upgrades your device to the base band which can't be unlocked so you better use Sn0wbreeze 2.8b8 to jailbreak iOS 5 GM.
