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 update 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!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.
