News for nerds, stuff that matters. TechCrunch. How Does Google Work? Apple. Macworld. 9to5 Mac. Redsn0w 0.9.9b8 Released. Published on 11-03-2011 02:49 PM Redsn0w 0.9.9b8 is fully compatible with the iOS 5.0.1 Beta released to developers yesterday.
Yesterday, Apple pushed out the iOS 5.0.1 Beta to developers which has fixed numerous bugs in iOS 5 and brings the beloved multitasking gestures back to the original iPad. It was reported that iOS 5.0.1 could have been jailbroken with redsn0w 0.9.9b7, although you would need to point redsn0w to the iOS 5.0 firmware file, and the jailbreak was tethered. Originally Posted by Dev-Team Blog 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). For those iPhone 3GS and iPhone 4 users who preserve their baseband, the Mac version can also produce the NO_BB_* custom IPSW's for 5.0.1. This is still a tethered jailbreak for all except old-bootrom 3GS users.
