Apple iPhone Dev team has now released first tethered jailbreak for iOS 5 beta testers. As reported earlier, Dev team has developed Redsn0w 0.9.8b1 with the help of Limera1n and tethered boot utilities.
Redsn0w 0.9.8b1 is only for Mac platform, and it’s specifically released for the official developers. If you’re not a developer, don’t pirate iOS 5 from illegal sources. Dev team members have suggested some important guidelines for iOS developers and Redsn0w users. Have a look at them below.
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.
The way redsn0w works, you will very likely be able to use this on upcoming iOS5 betas, just by continuing to point redsn0w at the 5.0b1 IPSW. So keep that IPSW handy!
Apple’s iOS 5 release is scheduled for this fall, so end users will have to wait for next few months for the final release. Developers can download the Redsn0w 0.9.8b1 file from following link.
