As you know iPhone Dev Team has released Redsn0w 0.9.8 beta 1 to jailbreak iOS 5 beta version on all idevices i.e., iPhone 4, iPhone 3GS, iPod Touch 3G, iPod Touch 4G and iPad 1 except iPad 2 . Here is the step by step guide on “How to Jailbreak iOS 5 with Redsnow 0.9.8”.
It is to be noted that Redsn0w 0.9.8 gives you tethered jailbreak meaning you have to connect your device with PC for a successful reboot. Before starting the actual process please read the following updates from iPhone Dev Team:
UNLOCKERS AND THOSE PRESERVING THEIR UNLOCKABLE BASEBANDS SHOULD STAY FAR AWAY FROM THIS! You will very likely lose your unlockable baseband if you try to install iOS 5.
THIS JAILBREAK IS INTENDED ONLY FOR DEVELOPERS OF JAILBROKEN APPS! There are just too many broken components (Apple’s official apps, 3rd-party App Store apps, Cydia apps, MobileSubstrate apps, etc) for this to be useful to anyone but those truly looking to fix bugs in their iOS 5 jailbroken apps. (Seriously!)
THIS REDSN0W WILL NOT HACTIVATE 5.0b1! You need to be an iOS developer with a registered UDID to get past all the new activation screens. PLEASE DON’T PIRATE APPLE SOFTWARE! Only registered devs with Macs can develop iOS applications, and only those people will have legitimate access to the beta IPSWs.
THIS IS A TETHERED JAILBREAK ONLY! No new exploits are being exposed with this jailbreak (it uses geohot’s limera1n bootrom exploit), but that comes at a cost. You will need to use redsn0w to “Just boot tethered now” to be able to use many things, including Cydia and Safari. If you see a white icon for Cydia, or if Cydia or Safari crash when you open them, it’s because you didn’t boot tethered.
IF YOU HAVE THE 06.15 BASEBAND ON YOUR 3GS…this redsn0w will get you past the iTunes restore error you’ll get when using the stock IPSW (nobody other than those with the 06.15 baseband should be going anywhere near the stock IPSW!).
Step 1: Download iOS 5 for your device. Only those who have Apple’s developer account can download this release. We don’t recommend any other source to download any beta iOS firmwares.
Step 2: Backup your device and update/restore it to iOS 5 as you have done in past during previous iOS updates.
Step 3: Download Redsnow for Mac and launch it.
Step 4: Browse for the downloaded iOS 5. Redsnow will process the firmware file and identify the file successfully.
Step 5: After clicking “Next” button, select “Install Cydia” option.
Step 6: Redsn0w will ask you to connect your device with PC after turning it off.
Step 7: Now follow the on-screen instructions to put your iOS 5 device into DFU mode.
Step 8: Now sit back and let Redsnow do its work. After Redsnow gives you “Done” message, close Redsnow software but leave the device connected with PC until your device reboots.
Step 9: As we have told you this jailbreak is tethered for now, meaning you’ll have to connect your device with PC, launch Redsnow and select “Just enter pwned DFU mode right now” from Redsnow options for successful reboot.
