It seems that the cat and mouse game is not going between Apple and iOS jailbreak hackers, after a couple of months work the new jailbreak hacker pod2g is able to discover the iOS 5.0.1 untethered exploit for the users on A4 devices except the newer devices, which Apple has released with A5 dual core processor. The new French hacker, pod2g, releases its discovered iOS 5.0.1 vulnerability along with the help of an iPhone Dev Team and Chronic Dev Team later last year, and the hacker promises to the jailbreak community that the A5 untethered jailbreak is a matter of days now, which means that he has been successfully able to crack the code for iPad 2 and iPhone 4S jailbreak.
However, earlier this month Apple has launched its third beta of iOS 5.1 to the developers along with new features, and fixes to old highlighted security, and other bugs on the iOS platform. iOS 5.1 beta 3 as well reveal that Siri is coming to the iPad 3, as the references present in the iOS 5.1 beta 3 It appears that iOS 5.1 beta 3 also come up with some bad news for the jailbreaking community, because according to the tweet of iPhone Developer Nadeem Ateyeh on Twitter to Veeence, iOS 5.1 beta fixes the latest released Corona untethered jailbreak exploit for iOS 5.0.1 on the latest beta.
So yeah, iOS 5.1 Beta 3 is NOT vulnerable to Corona. Update to 5.0.1 before it’s too late.

Which means once again, Apple has made the jailbreak community helpless with the fixing of iOS 5.0.1 untethered exploit Corona on iPhone devices. It is now highly recommended that if you are using any older iOS version on your device and want to upgrade the iOS version to the latest version, quickly move your device to iOS 5.0.1 and get the latest iOS 5.0.1 untethered jailbreak on your device and save the SHSH blobs for iOS 5.0 and iOS 5.0.1 because Apple has fixed the blobs’ monster trick which allows users to downgrade their devices to older iOS versions.
