redsn0w 0.9.6beta5 Download to Unlock iPhone 3G/3GS

Update 1: If you’re on iOS 4.2.1, and inject the 06.15 iPad baseband, you won’t be able to restore to stock firmware, or downgrade your baseband to 05.xx.

Explained by the Dev Team:

WARNING — YOU DO THIS AT YOUR OWN RISK!  PLEASE UNDERSTAND THE CONSEQUENCES OF UPDATING TO 06.15.

  1. There is no way to come back down from 06.15, and there’s no hiding the baseband version from Apple. You’ll be voiding your warranty in a very obvious way.
  2. If some future baseband comes out with a critical fix, you won’t be able to update to it if it remains down in the 05.xx sequence (then again, you wouldn’t update to it if you wanted to keep your unlock anyway).
  3. Starting with FW 4.2.1 if you have 06.15 on your iPhone you won’t ever be able to restore to stock firmware (it will fail).  You’ll need to only restore to custom IPSWs (then again, if you’re unlocker you should already be doing that).

Certainly don’t update to 06.15 if you don’t need to! Only do this if you need the unlock and you’re stuck on 05.14 or 05.15, and you’re willing to assume the above risks.

redsn0w 0.9.6beta5 is now available for download for OS X and Windows users. This updated version’s primary purpose is to inject the unlockable iPad baseband into iPhone 3G/3GS units, to be unlocked via ultrasn0w for iOS 4.2.1.

Here was the update posted by the iPhone Dev Team:

Update #2: The new redsn0w 0.9.6beta5 is out.  It gives both Windows and OSX users the ability to flash the iPad 06.15 baseband on iPhone3G or iPhone3GS.  It fetches the baseband files directly from Apple for now (the only IPSW you ever point it at is the stock IPSW for the FW on your iPhone right now).  There may be a long delay while it’s doing this (their servers are currently getting pounded).

  • OSX (SHA1 a322ec2c9e91993eca21abaf2e655bb44de3d7d4)
  • Windows (SHA1 7250416e17c3aea9838cdfc73712b38b025e2ed0) (Windows 7 and Vista users, please run redsn0w in “XP Compatiblity Mode”)

If you do flash your baseband via redsn0w, please keep it plugged into USB the whole time.  You don’t want your battery to die during the flash process!

Let us know how redsn0w works out for you. As always, follow the above procedures at your own risk.
