As you already know, the iPhone Dev Team have invited Mac testers for their untethered iOS 4.2.1 jailbreak ‘backup plan’ over the Christmas weekend. Now they have released this untethered version of Redsn0w 0.9.7b1 for Mac to the public. Windows users will have to wait a while.
The iPhone Dev Team have mentioned that they want to test Redsn0w on Mac first and if everything goes fine, then a Windows version will follow soon. Redsn0w 0.9.7 Beta 1 requires iOS 4.2 Beta 3 IPSW and also 4.2b3 SHSH hashes saved on Cydia. Quicken Mac 2018 Download. Use TinyUmbrella to save 4.2 Beta 3 SHSH for your iDevice ( you don’t need to be on 4.2Beta 3 to save it’s SHSH, TU will do it automatically do it for you). You can confirm 4.2b3 SHSH saved for your device from Cydia’s home page. This 4.2.1 untethered jailbreak currently works only for iPhone 4, iPod Touch 4, and iPad. IPhone 3GS (new bootrom) and iPod Touch 3G, 2G (MC) users will have to wait for the next version to make their jailbreak untethered. Here is the official release notes from the iPhone Dev Team: This is a beta tester program.
It’s not a general release! Things can go very wrong, so please don’t even consider testing if you have pictures or other media on your device that you haven’t backed up! For the same reason, please don’t participate if you rely on the ultrasn0w carrier unlock. Wait for the final version! Until we fix some sandbox issues with bluetooth, the bluetooth functionality is disabled.
