What’s new in Redsn0w v0.9.9b9b:

• Ability to downgrade from iOS 5.x for devices with SHSH blobs saved.
• 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 compatibility 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
• 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.
• Still a tethered jailbreak for all except old-bootrom 3GS users.

Redsn0w recognizes 5.0.1 automatically, meaning; you don’t have to go through the fuss of pointing Redsn0w at iOS 5 manually then go ahead with the tether-jailbreak.
