Even though Apple released iOS 5 Golden Master more than a month after the last beta release, the good news is that it is possible to jailbreak it.
Few weeks back iPhone Dev team had released a new version of Redsn0w – v0.9.9 with a number of new features and improvements. The new version no longer need the full version of the firmware file. The latest version of Redsn0w will automatically download the files required for the jailbreak directly from Apple’s servers.
Dev team has provided the following information on their blog about the latest update:
redsn0w has been updated to 0.9.9b3 to auto-detect iOS5 GM firmware. Remember: it’s still tethered for all devices except for iPhone 3GS with old bootrom. If you don’t use redsn0w to “Just boot” at power up, all jailbreak apps (and even some native ones like MobileSafari) will fail to launch.
If you already jailbroke the GM by pointing an older redsn0w at the beta7 IPSW, there’s no need to re-run the full jailbreak step again…just use this newer one to make the tethered boot easier 🙂
Redsn0w 0.9.9b3 supports the following iOS 5 devices:
iPhone 4 (GSM)
Redsn0w 0.9.9b3 supports only a tethered jailbreak, except for iPhone 3GS with old bootrom which is untetherd. With a tethered jailbreak you need to connect your iOS device to the computer on every reboot. It still doesn’t support iPad 2, so it is unlikely to support iPhone 4S that was unveiled at Let’s Talk iPhone event.
Dev team has just released a new version of Redsn0w – Redsn0w 0.9.9b3a for Windows users to fix a caching bug. They explain:
Update #11a: We’ve replaced the Windows version of 0.9.9b3 with 0.9.9b3a. The new version fixes a caching bug that affected only Windows users — point it one more time at your iOS5GM IPSW, and from then on you won’t have to point at it again.
As a special bonus to Windows users, we’ve made it so that if you make a copy of redsn0w.exe and name it something like “justboot.exe” (anything with the word “boot” in it), it will start up in “Just Boot tethered” mode. That way you don’t have to click on any buttons at all to boot tethered! 🙂
We’ve updated the download link accordingly.
As always, let us know how it goes.
