We have new jailbreak details for you, and we’re still talking about a tethered (or semi-tethered) iOS 5 jailbreak as the untethered version is yet to see the light of day. But as pod2g is working on his own untethered jailbreak solution, the iPhone Dev Team has updated its Redsn0w jailbreak tool to version 0.9.9b9.

The iPhone 4S and iPad 2, being new device that sport the new A5 dual-core chip, can’t be jailbroken at this time by Redsn0w or any other tool. The iPhone Dev Team achieved a preliminary iPhone 4S jailbreak, and there was even talk about an exclusive iPhone 4S unlock (with no iPhone 4 support) but such tools were not released yet.

Apple is expected to launch iOS 5.1 in the near future, and hackers may be interested in waiting a while longer before launching new jailbreak and/or unlock tools in the wild. Redsn0w will continue to work with any iOS version, therefore updating the tool – even if it offers just a tethered jailbreak – can be done safely.

The new tool works on iOS 5.0 and iOS 5.0.1 devices, but brings a lot of new features and explanations to the table, as follows:

• native support for 5.0.1 (no need to point redsn0w at 5.0 IPSW or use command-line args). Support automatically extends to all of redsn0w’s various functions: “Jailbreak”, “Just boot”, “Fetch blobs”, “Stitch blobs”, “Recovery Fix”
• iBooks fixed in 5.0 and 5.0.1. This is a targeted fix that doesn’t remove entire sandbox mechanism. 5.x users already using redsn0w “Just Boot” can just use the new version without redoing entire jailbreak again
• 3GS old-bootrom owners can now create custom IPSWs without blobs
• ultrasn0w compatability update (i.e. same baseband requirements) for 5.0.1 will be available on Cydia Monday
• support for newer 8GB iPhone4 (which until now had problems with “Fetch blobs”). Thanks to @JKjeepnJeff for loaning us one of these newer i4 units for testing!
• allows Windows users (not just OS X users) to use the “Custom” button to create IPSWs without baseband updates. (Update: please use 0.9.9b9b for this!)
• accommodates APTickets in 5.x (until next Apple countermove). APTickets are crypto-verified before submitting to Cydia, just like the main blobs. Cydia server support for sending back the APTickets is upcoming. For now, use stitched IPSWs for 5.x. Due to APTickets, stitched 5.x IPSWs now require user to start in “Pwned DFU” mode
• Support added for stitching 4.x blobs to iPad2-GSM IPSWs. Similar to @notcom’s TinyCFW but doesn’t require lots of RAM or a TSS-assisted restore. Won’t work for iPad2 5.x blobs (or iPhone4S at all) until a bootrom-level exploit is out
• top line now shows whether (and where) a redsn0w update is available, or if the version being run is the latest. Uses DNS TXT record to alleviate any concerns about snooping
• no 5.1 beta support at this time (major apps like Cydia are not yet compatible)
• @pod2g has been doing a great job porting his 5.x untether…check his blog for updates!
• Owners of newer 3GS iPhones must not flash the iPad baseband. The iPad baseband will not work on 3GS iPhones built later than 2011 week 35. You have a week 35 or later device if your serial # starts with xx135.

While we do provide consistent information on jailbreaking and/or rooting devices, we certainly don’t encourage you to go down that path. In case you are interested in pursuing such jailbreaking endeavors remember that you bear the full responsibility for whatever happens. And also make sure you backup your devices and follow the available step-by-step instructions before going forward.
