iOS 5.1 Patches Corona Untethered Jailbreak! Get on iOS 5.0.1 while you can!



Well can't say I didn't see this coming but yes it's been confirmed that iOS 5.1 beta 3 closes the exploit for the Corona untethered jailbreak. iOS 5.1 is currently in beta, but will be released to the public very soon.

If you want an untethered jailbreak for iOS 5, then we recommend that you stay on iOS 5.0.1, or you CONSIDER updating to iOS 5.0.1 if you have not already done so. Since iOS 5.1 closes the exploits used in iOS 5.0.1 with the Corona untether, more exploits will need to be found to jailbreak iOS 5.1 untethered. A4 devices will likely have a tethered jailbreak for iOS 5.1 at least because of the fact that A4 devices have a bootrom exploit. A5 devices on the other hand won't be so lucky. A5 devices also currently have no way to downgrade firmware, so again I emphasize, if you want an untethered jailbreak then get on iOS 5.0.1 while you have the chance! 

Another thing worth noting is that Crapple usually continues to sign the previous FW for short amount of time AFTER a new FW is released. So if you have an iPad 2 that is Jailbroken on iOS 4.3.3 and you're not wanting to update to iOS 5.0.1 just yet and want to try to wait until the last minute possible so that you can retain your iOS 4.3.3 Jailbreak you could always wait it out and hopefully an iOS 5.0.1 A5 Jailbreak will be released BEFORE iOS 5.1 drops. Otherwise like I said you could wait till the very last second and hope that when iOS 5.1 drops you can still update to iOS 5.0.1 that is if you're willing to take that risk. Like I said in the past Crapple has continued to sign the previous FW for a short amount of time but that doesn't mean that things can't/won't change.

If you have an iPhone 4S then there is NO REASON for you to stay behind on previous FW's. Make sure you UPDATE TO iOS 5.0.1 ASAP!!! Also take note that there are TWO VERSIONS of iOS 5.0.1 for the iPhone 4S. A newer version was released shortly after the first release to fix a "NO SIM" issue. The one that you want to be using has a build name of Telluride 9A406 and here is the OFFICIAL DOWNLOAD LINK!

As always make sure that you BACKUP your APticket and SHSH blobs. Even though A5 device users cannot downgrade at this time you should still save them anyways that way when/if a solution to downgrading is found you will be able to downgrade. I would suggest backing them up to YOUR COMPUTER and NOT relying on Cydia to save them for you because you never know what might happen or if Cydia is having server issues and you need to restore your device you won't be able to. So it's best to back them up yourself and use TinyUmbrella or iFaith for restoring.
