For those who have been keeping tabs on the happenings in the tech industry, you should be aware that Apple has already released their most advanced mobile operating system yet, the iOS 5. And since this is a major firmware update, you can trust that the jailbreak community is hard at work to bring us the most relevant jailbreak solution. Yes, iOS 5 can be jailbroken, albeit only a tethered jailbreak at the moment using the Redsn0w tool. And now it seems that iPhone Dev Team has made another update to Redsn0w, check out the changes below.
iPhone Dev Team's Redsn0w 0.9.9b6 is now available for download. This release came after a week since 0.9.9b5 was made available. Windows users who have been clamoring for 0.9.9b5 can now rejoice because this build caters both to Windows and Mac (although the Custom IPSW is not yet available in Windows on this build). According to the iPhone Dev Team, this update is both a functional fix and cosmetic fix for iOS 5 jailbreakers. There is one notable fix for 3GS owners with 06.15 baseband, as this build eliminates the network crash that happens each time location services is used in iOS 5.
From the iPhone Dev Team Blog:
We’ve released version 0.9.9b6 of redsn0w, with both a functional fix and cosmetic fix for iOS5 jailbreakers. For iPhone3GS owners with the 06.15 baseband, this redsn0w eliminates the network crash you saw when using Location Services in iOS5 (in fact, you don’t even need to disable Location Services anymore during the initial setup). The cosmetic fix is to the visual countdown you see when going into DFU mode.
It’s okay to re-run this redsn0w over an existing device jailbroken at iOS5. Just choose “Jailbreak” again and de-select Cydia (in other words, all the checkboxes will be unchecked). If you are lucky enough to have an old-bootrom iPhone3GS, please pre-select the IPSW first (redsn0w can’t yet auto-detect the FW version of your old-bootrom 3GS if it’s already been jailbroken).
Another notable feature of Redsn0w 0.9.9b6 (which was also present in 0.9.9b5), is that is gives users the ability to preserve their baseband by providing an option to create their own custom IPSW (the Custom IPSW option is currently for Mac only). A must have feature for those who are relying on Gevey SIM or Ultrasn0w unlocks. If you are using Gevey SIM to unlock your iPhone 4 on iOS 5, then you might want to check our detailed guide here.
If you are jailbreaking iOS 5.0 into your iPhone, iPad or iPod touch using Redsn0w 0.9.9b6, the process should be pretty similar to past builds, so we refer you to our Redsn0w iOS 5.0 tethered jailbreak guide. Keep in mind that this is a tethered jailbreak which means that each time your device shuts down or reboots you will need to connect it to a computer and run Redsn0w in order to tether boot it and be usable again. If you are looking for an untethered solution, unfortunately it is not yet available. But as we have previously reported, Chronic Dev Team has already covered that so it might just be a matter of time before we see an iOS 5 untethered jailbreak. Hopefully!
