The iPhone Dev-Team is on the roll. After the release of iOS 6 Beta 1, they updated the tool Redsn0w to v0.9.13Dev1 to Jailbreak iPhone 3GS and older A4 Devices. This version of Redsn0w is specifically for Developers who want to update their Jailbreak Apps for iOS 6. This Tethered Jailbreak by redsn0w doesn’t puts on any new exploit or anything, this is the same old Jailbreak method using the Limera1n exploit that GeoHot introduced at the time of iOS 4.x.x. This update of Redsn0w v0.9.13dev1 will not add Cydia onto your iPhone because the status of Cydia is broken on iOS 6 for the time being and it won’t even hactivate your iPhone.
Hactivate means to by pass the lock screen. This release is only for developers and unlockers, hactivaters should stay away from this release. They should wait till fall for the official iOS 6 releases. As the Jailbreak for this iOS 6 beta 1 remains Tethered, so there are some limitations for the Developers who want to test this Jailbreak. The limitations are that their Apps with Safari won’t work are the Jailbreak because they will need to Boot tethered after the Jailbreak is done. After you have booted Tethered, the Apps will work again. This Tethered Jailbreak wont be adding Cydia, it will only add SSH Support or AFC2D support for the root access of iOS 6 beta 1.
