The iPhone Dev Team is really rolling out these redsn0w 0.9.7 betas quickly. Just yesterday, redsn0w 0.9.7b5 was pushed out ( Mac only ) which fixed Bluetooth issues that users were facing. Today, the 6th beta has been released which fixes Skype issues. Also, you can now run beta 6 over beta 5 instead of restoring iOS and then running the newest beta of redsn0w. But the Dev Team wants users to test the tool both ways, by clean restore and also by upgrading from already jailbroken.
Here’s the complete update by the iPhone Dev Team:
The sixth beta is now available (testers ONLY please!). This version fixes Skype (and as expected all along, the Skype issue turns out to be unrelated to sandbox patches). Please do not pirate the 4.2b3 IPSW! Only those enrolled in the iPhone Developer program have legitimate access to that IPSW using these links (the links won’t work unless you’re a legit developer currently logged in).
Unlike the last few betas, you can freely run beta6 over beta5 without a problem (but for testing purposes, we’d really like people to try both ways….from stock, and from already jailbroken). If all you want to do is fix Skype and you’re already untethered using beta5, just run beta6 and deselect every checkbox.
Now that the sandbox, Bluetooth, and Skype issues are fixed, our next priority is porting Monte back to 4.1. We’ll also try to make the Windows version less painfully slow.
A Windows version of redsn0w 0.9.7 hasn’t been released yet because it’s forced to use the hard disk instead of the RAM while processing IPSW ( iOS device firmware ) files. Priorities for the next release now include fixing the Windows version as well as porting Monte to 4.1
Meanwhile, the Chronic Dev Team is aiming to push out the next greenpois0n update with untethered jailbreak support for iOS 4.2.1 on iPhone, iPad and iPod touch. Which of these dev teams will be first to provide an untethered jailbreak for iOS 4.2.1? Only time will tell.
