Released just yesterday, iOS 5.0.1 Beta was jailbroken already using Redsn0w (by pointing it to the final iOS 5.0 firmware file). The iPhone Dev-Team has now released an updated version of Redsn0w which can recognize the 5.0.1 firmware file so that you don’t have to play the “point at 5.0 IPSW” trick.
iOS 5.0.1 beta was seeded to developers recently. As you may have guessed from the small bump in version number, the update does not bring any news features but does fix a lot of bugs and improves performance. iOS 5.0.1 fixes the battery drain issue, patches the hole that caused the iPad 2 Smart Cover security issue, adds multitasking gestures for original iPad, contains security improvements and fixes general bugs.
If you’re a developer and already have iOS 5.0.1 beta installed on your device, you can easily jailbreak it using the latest version of popular jailbreaking tool redsn0w – v0.9.9b8 – which you can download from the end of this post.
From the iPhone Dev-Team:
redsn0w version 0.9.9b8 will natively recognize the 5.0.1 beta that Apple let developers start testing this week (so you don’t have to play the “point at 5.0 IPSW” trick).
Because the IPSW isn’t public, you’ll still need to provide it once to redsn0w (at which point it will cache all the important pieces so you don’t need to select it again).
This is still a tethered jailbreak for all except old-bootrom 3GS users.
The process is quite simple, after downloading iOS 5.0.1 beta’s IPSW from Dev Center, you point redsn0w 0.9.9b8 to it which then works its magic on it and then jailbreaks your supported iOS device. Full step by step instructions on how to use Redsn0w to jailbreak iOS 5.0.1 can be found here.
This is, of course, a tethered jailbreak meaning you will have to connect your iOS device with a computer to boot into the jailbroken state. This is obviously quite cumbersome and, thankfully, there is a bit of a solution for it: a Cydia package called SemiTether allows users to reboot into jailbroken state with limited functionality. Users will have to be connected with a PC to get full functionality, so SemiTether isn’t the best solution to the problem but it does make things a little easier for jailbreaking enthusiasts on iOS 5. After jailbreaking, you can follow our guide on how to install SemiTether. While it still seems far, far away, you can learn more about untethered jailbreak for iOS 5 here.
