Tutorial: Jailbreak iOS 5 Beta 4 On iPhone 4, 3GS, iPad, iPod touch Using Redsn0w 0.9.8
Shortly ago, iOS 5 Beta 4 was released to Apple developers. Those who have installed it are probably wondering how easy it will be to jailbreak the new system. It turns out you can do it the same way you’d do with all previous builds of iOS 5, using the just released version of Redsn0w.
Redsn0w for iOS 5 has received a minor update to make it compatible with iOS 5 Beta 4. The iPhone Dev Team, which authored this tweak, points out that this build, much like iOS 5 itself, is in beta form and should only be used by developers to test apps in the new iOS.
It should also be noted that if you jailbreak your device on iOS 5, you wont get OTA updates from Apple, as explained by MuscleNerd of iPhone Dev-Team:
The 5.0b4 OTA update won’t work on JB devices due to an explicit check of /Applications..almost like a present from Apple
NOTE: It appears that by design, the OTA update that became available starting with iOS 5 beta4 will *not* be automatically applied to jailbroken devices. That’s a relief to those who don’t want to lose their jailbreak via OTA pushes. If you’re jailbroken, you’ll need to use the standard iTunes method to get to iOS 5 beta4.
Redsn0w is fairly easy to install and use, since the program itself provides concise instructions on all the manual steps that need to be followed. While that may be true, it’s recommended that you have basic knowledge on basic iOS maintenance tasks, including restoring and entering DFU mode, in order to proceed. Also, remember that jailbreaking your device will void your warranty. You can follow the full tutorial here.
This is a tethered jailbreak, which means that the device will have to be plugged into the computer whenever it’s powered on, in order to be booted into a jailbroken state. It wouldn’t be worth for developers to work on an untethered method at this point, definitely not anytime before the final version of iOS finally ships.
iOS 5 is the major release of Apple’s mobile operating system that runs on iPhones, iPod touches and iPads. The new iOS includes many features, some of them long-awaited by the iOS community, including a revamped and less intrusive notification system, enhancements to Mobile Safari, especially on the iPad, and system-wide Twitter integration. It was first unveiled at this year’s WWDC, which stands for Worldwide Developer Conference, with the first beta coming out on the same day, followed by several other builds over the last few weeks.
In order to get iOS 5 legally, users should be registered Apple developers. Anyone is eligible to get a developer registration for $99 per year, which will give members access to all future beta builds of iOS, along with developer-oriented documentation and tools. Registrations can be purchased from Apple’s developer website.
