iPhone 4 Unlock: Ultrasn0w Update für iOS 5.0.1 Mit dem neuesten Update kommt Weihnachten für Benutzer eines iPhone 4 und iPhone 3GS mit (einer mit Hilfe von redsn0w o.ä. erstellten Version von) iOS 5.0.1 schon etwas früher: Bestehende Unlocker bekommen mit ultrasn0w 1.2.4 das ersehnte Update, um auch die neueste öffentliche iOS-Version inkl. Unlock verwenden zu können.
An den unterstützten Basebands hat sich aber leider nichts geändert: Unterstützt werden 04.26.08, 05.11.07, 05.12.01, 05.13.04, und 06.15.00 am iPhone 3G(S), sowie 01.59.00 am .

Das dazu passende Update auf RedSn0w 0.9.9b9b löst nicht nur eventuelle Unlock-Probleme für mit iPad-, sondern bringt einige zusätzliche Neuerungen (zu finden im Anschluss).

Achtung für alle mit einem neuen iPhone 3GS, das ab Woche 35 2011 verkauft wurde: Diese iPhones sind mit den aktuellen Methoden nicht Jailbreak-fähig, und sollten auf keinen Fall das Aufspielen einer custom Firmware (z.B. mit Redsn0w versuchen). Wenn ihr euch nicht sicher seid, wann euer iPhone gebaut/verkauft wurde: Seriennummern, die mit xx135 beginnen, bezeichnen iPhone 3GS der neuesten Version.

Update #17: 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 , 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
  • 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.

Update #17b: Version 0.9.9b9b enables the “Custom” button for Windows users, and make the 3GS week 35 warning a more explicit part of the process.
