iPhone 4S Jailbreak Testing

Currently it looks like pod2g is very close to an untethered jailbreak for the iPhone, iPad and iPod Touch. Currently he is working through issues with the A5 powered iPhone 4S and iPad 2, an update on his progress is expected tomorrow. As for now, redsn0w has been updated to 0.9.9b9b to offer full support for those in the jailbreak community stuck in iOS 5.0.1.

Here is the latest on redsn0w from the iPhone Dev Team blog:

The holiday season is almost here (Happy Holidays!) so we realize everyone is busy (especially @pod2g!). And even though we always recommend that jailbreakers stay where they are until a new untethered JB comes out, that’s not always possible. So we’ve updated redsn0w for those who may have found themselves at iOS 5.0.1, and added some other useful features too:
  • 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
  • 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.
This is still a tethered jailbreak for all except old-bootrom 3GS users.
