The infamous iPhone Dev Team has posted a download link for the latest Mac version of Redsn0w (Windows version in the works) which works against iOS 5, the newest mobile OS from Apple.
The Team informs on its blog that redsn0w has been updated to 0.9.9b5 to include the public URLs for the iOS 5 IPSW files for all supported devices.
“This way, first-time iOS5 jailbreakers don’t need to supply the IPSW file manually,” the Team writes.
The hackers confirm that redsn0w currently still provides a ‘tethered’ jailbreak, meaning users will have to always connect their handset to the jailbreak machine when a reboot is necessary. An iPhone 3GS model is the exception.
“It’s still a tethered jailbreak on all except the old-bootrom iPhone3GS, and it doesn’t apply to iPad2 or the upcoming iPhone4S,” the team writes, thus confirming which devices work with the jailbreak utility, and which don’t.
The tinkerers claim they’ve build some of PwnageTool’s functionality into Redsn0w, therefore they are holding off the release of a new PwnageTool version. The main reason is the ‘tethered’ nature of the hack.
According to their blog entry, “The new ‘Custom IPSW’ button on the Extras screen will create a custom IPSW without the baseband update for 4.3.3 or 5.0gm (iPhone3GS and iPhone4 only, for now).”
Jailbreakers are warned to avoid accidental restoration to the stock IPSW after creating the custom one.
The Team’s post ends with a promise to try and deliver normal compatibility for existing ultrasn0w unlockers and a fix to the iBooks issue on jailbroken iOS 5 devices.
iOS 5 is the biggest software update Apple ever released for its mobile OS containing over 200 new features and improvements, including a new Notification system, iMessage, Newsstand, a coll Reminders app, Twtter integration, Camera and Mail improvements, AirPlay mirroring and, of course, iCloud support, to name some of they key additions.
